TYPE W INSTRUMENT AND CONTROL SWITCHES In 1988, Electroswitch acquired the Type W Switches and Relays from Westinghouse Corporation for the purpose of maintaining a high level of support and assistance to existing customers in the utility industry. Since that time, many changes have been made in switch technology and these models have been replaced. However, Electroswitch continues to offer the Type W Switches for customers needing replacements into existing systems that would require panel rework.
LOCK-OUT RELAYS E By definition the Lock-Out Relay plays a pivotal role in the most crucial utility applications. In an emergency, Lock-Out Relay performance can spell the difference between a routine outage and the destruction of expensive equipment. Protect your system and safeguard your personnel with the industry standard for safety and reliability. There’s NEVER A DOUBT with the Electroswitch family of Lock-Out Relays.
NEDW UC T SERIES 24 LOR With Lighted Target Nameplate PRO Lighted Target Nameplates Save Panel Space and Reduce Costs The Electroswitch Series 24 Lock-Out Relay, the Utility Industry Standard for Quality and Reliability, is now available with: • Integral Coil Monitoring with LED Display and SCADA Feedback. • LED Indication of Existing Fault Signal. The Lock-Out Relay fills one of the most critical needs in the utility industry protection scheme.
SERIES 24 LOCK-OUT RELAYS FEATURES Typical Contact Deck Arrangement Contact Ratings Contact ratings for LOR Interrupting Rating (AMPS) Basic LOR Deck Layout The blade and terminal configuration enables the use of multiple contacts in the same deck, and simple stacking procedures enable the fabrication of many independent contacts in one relay.
ELECTROSWITCH SERIES 24 LOCK-OUT RELAYS OPTIONS Manual Reset LOR Electric Reset LOR LOR T Closing S1 energizes the linear solenoid which releases the trigger mechanism and causes the LOR to snap to the Trip position. The control deck blades rotate to interrupt current flow to the coil. Shown in Reset position The Electric Reset LOR is tripped by the same method as the Manual Reset LOR. In the Trip position, closing S2 operates relay K1 which closes relay contact K1.

ELECTROSWITCHTYPE WL-2 LOCK-OUT RELAYS The Type WL-2 Lock-Out Relay was designed and manufactured by Westinghouse to provide dependable tripping in a variety of protection schemes. Since acquiring the line in 1988, Electroswitch has supplied hundreds of these rugged, reliable relays for both new applications as well as replacement units for the enormous installed base of WL-2s all over the world.

ELECTROSWITCH TYPE WL LOCK-OUT RELAY The Type WL Lock-Out Relay product line was also acquired from Westinghouse in 1988. Countless Type WLs are still providing reliable protection in older facilities decades after they were first installed. Electroswitch is pleased to announce that we can provide replacement units for most of the WLs still in service.
CONTROL SWITCH RELAYS E Electroswitch Control Switch Relays (CSR) combine the function of a control switch with a remote controlled solenoid allowing one device to do both the manual and supervisory control function in the control of power circuit breakers. They eliminate the need to redesign substations for redundant separate relays when manual substations convert to supervisory control. CSRs provide manual or electric control switch operation by supervisory control.
CONTROL SWITCH RELAYS E Contact Ratings Transient Protection The CSR Control Switch Relay is designed and tested to operate reliably in a normal power industry environment. This includes being subjected to transients on the control bus up to 3.5KV. Since the CSR is normally isolated from the bus, it will experience transients only if they occur in the operating mode. This precludes the possibility of a detrimental, accumulating affect over the life of the unit.
CONTROL SWITCH RELAYS Circuit A has a factory adjustable time delay that holds the CSR in the commanded position for 1 to 3 sec. The command contact closure time should be greater than 100 msec and less than the time delay setting (to avoid pumping). This circuit is not recommended for applications where the SCADA timing sequence is greater than three seconds as it will cause pumping. POS.

ELECTROSWITCH CONTROL SWITCH RELAYS WITH SCADA DISABLE The Control Switch Relay with SCADA Disable (CSR/SD) operates like a standard CSR, allowing both SCADA and manual operation. Pushing in the handle disables remote operation leaving only Local/Manual operation possible, allowing testing and service to be performed safely. In addition, the CSR/SD also provides 2 N/O and 2 N/C contacts, push activated, for customer use as SCADA feedback of status indication.
ELECTROSWITCH SELECTOR SWITCH RELAYS The Series 24 Selector Switch Relay (SSR) is an auxiliary relay that combines electrical and manual operation in a single unit for multiposition applications. Basically a unidirectional (CCW) stepping switch, the SSR can be used in any 2 to 8 position application. The SSR is ideally suited for tapswitch applications or any other multiposition application where simple or complicated contacting is used.
LATCHING SWITCH RELAYS The electrical power industry has a great variety of requirements for latching type auxiliary relays to provide maintained contacts -- both N/C and N/O. Often, manually operated switches are used in conjunction with traditional relays to provide the "maintained" function. However, traditional protective relays have limitations as to the number of contacts available and their ability to withstand seismic vibration.

CONSTRUCTION DETAILS SERIES 24 AND 31 DETENT-ACTION SWITCHES Electroswitch Detent Switches Electroswitch Detent Switches are a heavy-duty design that is very versatile and enables standard units to satisfy a great variety of complex switching applications. They are modular in that several subassemblies are stacked together to form a rigid rugged device. Figure 1 shows a cut-away view exposing the basic components.
CONSTRUCTION DETAILS SERIES 101 SNAP-ACTION SWITCHES Snap Action Switches Snap Action Switches use a design that enables them to combine a small number of basic parts to satisfy a wide variety of requirements for selector and control switching of power circuits. Standard switches built with this design for15-, 40-, 60-, and 200-ampere capacities are listed in this catalog.
CONSTRUCTION DETAILS SERIES 20 CAM-ACTION SWITCHES Cam-Action Switches The design principle allows the combination of a relatively small number of basic parts to satisfy a wide variety of requirements for selector and control switching in power circuits. The Mechanical Design The switch features a modular design with switching decks (3) stacked with a detent mechanism deck (6), a mounting plate (12), and a handle (13). A steel shaft (10) couples the handle to the operating parts.
CONSTRUCTION DETAILS TYPE W-2 INSTRUMENT AND CONTROL SWITCHES Design Features General Construction The W-2 Switch consists essentially of an operating handle, faceplate, control housing, contact frame assembly and rotor assembly. It can be built up in any number of stages from 1 to 8, where stages are clamped together, and to the control housing by two tie bolts. A steel operating shaft ties the contact rotors together. A metal cover on the rear holds the position stop pins and retains the shaft.
ELECTROSWITCH – E TESTING UL and CSA Ratings All About Testing Switches are tested in many ways to prove their capabilities and reliably. Electroswitch uses a combination of test methods to provide meaningful data for all applications. These include: 1. Cycle it mechanically until it breaks. This is usually an academic test since switches that do not switch electric power are not needed.
