General Information Introduction Siemens SB Encased Systems Breakers bridge the performance gap between Molded Case Circuit Breakers (MCCB) and Low Voltage Power Circuit Breakers (LVPCB). Modern computer-aided design and manufacturing tools were used to effectively blend the technologies of the MCCB and LVPCB. This combination has resulted in a family of encased systems circuit breakers that exhibit the most desirable characteristics of each of the parent technologies.
General Information Frame Sizes and Frame Ampere Ratings IEC 947-2 Ratings (SBS Units Only) SB breakers come in four frame sizes with MAX ratings ranging from 400A to 5000A. All frames are rated for 100% continuous operation.
General Information NOTE: For more information on other standard and optional trip unit features, see Siemens Electronic Trip Units for SB Encased Systems Breakers Information and Instruction Guide Bulletin IPIM-2203 and the Sentron Systems Breaker Energy Communicating Trip Unit Information and Instruction Guide Bulletin IPIM-2208. This patented construction provides a higher interrupting capacity within a smaller housing than can be achieved by more conventional construction.
General Information Compact Size For space-limited installations, the 1200A and 2000A frames offer a common width of 15 1/2 inches, a common depth of only 12 1/8 inches, a common mounting footprint, and common bus center lines. This compact, shallow depth (even with drawout breakers) permits stacking of six 800A or 1200A breakers or four 2000A breakers in a standard switchboard. This packaging is made possible by the insulated-encased construction and thermal performance of the SB breaker.
Description Stationary and Moveable Drawout Elements Simplified Minimum Depth Drawout Mechanism The two elements of a drawout constructed SB Encased Systems Breaker are the stationary drawout element and the moveable drawout element. The stationary drawout element mounts from the front or bottom into a standard switchboard. Bottom mounting flanges are provided for optional mounting arrangements. The moveable drawout element mounts onto the stationary drawout element’s two extension rails.
Description Electronic Trip Units For Siemens SB Encased Systems Breakers Trip Units Advanced True RMS Current Sensing Two types of trip unit are available for the SB breakers. The TL (standard) Trip Unit features a full range of industry standard protective settings.

Carefully uncrate the moveable drawout element and remove all packing material with the exception of the wire ties holding the racking pump handle in place.
Frame Installation Instructions Stationary, Moveable, and Fixed-Mounted Drawout Elements To correctly engage the moveable drawout element with the racking mechanism, the crank pins on the sides of the moveable drawout element must be in the Unlocked position as illustrated and the release lever must be in the Up position. During shipping and handling, the crank pins may have rotated out of position. If so, rotate them to the correct position.
Installation Instructions Electronic Trip Unit Note: If you are installing a SB-EC Trip Unit, refer to the Information and Instruction Guide for this device (IPIM2208). To install the trip unit, remove the breaker’s front cover. This is done by removing the four recessed Phillips head screws in positions 2, 3, 6, and 7, as well as the four Phillips head screws in positions 1, 4, 5, and 8, which hold the front cover in place.
Installation Instructions Electronic Trip Unit Before attempting to install the trip unit, check the label on the side of the unit to make sure that it is the correct unit for the SB breaker. A built-in rejection scheme will prevent the installation of a trip unit into a breaker for which it is not intended. 4. Check label on side of trip unit. This scheme consists of two pins on the support plate on which the trip unit will set and two matching holes in the bottom of the trip unit.
Installation Instructions Electronic Trip Unit Rating Plug 8. Replace circuit breaker front cover. Replace the front cover. Then, replace the eight front cover screws. ! CAUTION Do not attempt to install a rating plug with the breaker Closed or Charged. Make certain breaker is Open and Discharged as shown above. Personal injury or mechanical damage may occur. Verify that breaker is Open before inserting or removing a rating plug.
Installation Instructions Rating Plug ! CAUTION Do not attempt to force an incorrect rating plug into a trip unit. Mechanical damage may occur. The receptacle in the trip unit has been keyed to prevent the insertion of an incorrect rating plug. 5. To replace the cover, bow it slightly in the middle and snap into place. 3. Check label on the rating plug. Check the rating plug label to verify that it is the correct plug for the trip unit.
Operating Instructions Operating the SB Encased Systems Breaker General Instructions Operating the SB Breaker Instructions for charging the stored energy mechanism, closing and opening the breaker, and positioning and rotating the moveable drawout elements of the drawout-constructed SB breakers are presented in this section. The trip unit’s standard test and monitoring functions are also presented.
Operating Instructions Operating the SB Encased Systems Breaker Discharged indicator points to Spring Charged. The charging handle returns to the stowed position when released. While manually charging the breaker with the charging handle, do not depress the Push-to-Close or Push-to-Open push buttons. If an optional electric motor operator is employed, the electric operator automatically recharges the stored energy mechanism when the breaker is closed.
Operating Instructions Operating the SB Encased Systems Breaker Discharging the Stored Energy Mechanism Without Closing the SB Breaker Discharging the energy in the stored energy mechanism without closing the breaker creates an abnormally high shock condition on the breaker. Avoid this procedure except for safety and/or emergency reasons. To discharge the energy, push and hold the Open pushbutton and then push the Close pushbutton.
Operating Instructions Manipulating the Moveable Drawout Element Manipulating the Moveable Drawout Element There are four positions of the moveable drawout element. These four positions are defined as Connected, Test, Unlocked, and Unlocked/Withdrawn. The connected position is the normal operating position of the breaker. In this position the primary stabs and secondary contacts are connected and the moveable drawout element is locked into position.
Operating Instructions Manipulating the Moveable Drawout Element Directional Shift Lever Racking Controls A built-in, low-force pump handle and two control levers are used to rack the moveable drawout element between the Connected, Test, and Unlocked positions. The directional shift lever determines the direction the movable drawout element will move when it is racked. The lever has three positions: racking-out, neutral, and racking-in.
Operating Instructions Manipulating the Moveable Drawout Element Racking Pump Handle Drawout Position Indicator A low-force pump handle is used to rack the moveable drawout element. The pump handle is an integral part of the racking mechanism, eliminating the need for an auxiliary racking device. If there is any resistance in returning the pump handle to the stowed position, set the directional shift lever to the neutral position. The racking pump handle can then be returned to the stowed position.
Operating Instructions Manipulating the Moveable Drawout Element Fully Withdrawn and Unlocked Positions To move the moveable drawout element from the Fully Withdrawn position to the Unlocked position, push toward the bus connections until the moveable drawout element hits a solid stop. The secondary disconnects on both sides of the moveable and stationary drawout elements will mate as the moveable drawout element moves into the Unlocked position.
Operating Instructions Manipulating the Moveable Drawout Element ! CAUTION To avoid damaging the racking mechanism, always pull the release lever before racking the moveable drawout element. Unlocked Position to Test Position Racking the moveable drawout element from the Unlocked position to the Test position engages the moveable drawout element with the stationary drawout element.
