Lighting Contactors
CR460 Series
Application Information
CR460 lighting contactors switch ballast (fluorescent or HID), tungsten and general use
loads and carry motor load, resistive and pilot duty ratings as well.
CR463L Electrically Held Contactors
Operational Mode
• 3-wire control is typically used when control is desired from multiple locations. The
contactor is operated from a momentary pilot device and requires an auxiliary contact
to be used as a holding interlock.
• 2-wire control is used for single location control with power continuously supplied to
the coil for contactor operation.
CR463M Mechanically Held Contactors
A mechanical latch with a 2- or 3-wire electronic control module delivers reliable
performance and protection from such application abnormalities as line noise,
leakage currents from controller outputs, or short repetitive commands burst from
faulty controllers.
Mechanical Operation
• Latches after contactor command and removes coil from circuit for
noise-free opera
tion
• Eliminates all coil losses after contactor is latched
Control Module
• Coil operation and control circuit at same or different voltages
• Allows longer control wiring runs
• Microprocessor validates control signal before operation
―will not respond to momentary voltage spikes or noise
―operation command has built in delay (0.4 sec) to avoid multiple short-term
commands that can cause contact fatig
ue or failure
―feedback loop prevents contactor from getting out of sequence with switches,
even after power failures
Operational Modes
• 3 wire control is the choice for use with momentary devices allowing operation from
multiple locations
―a momentary pulse of energy operates contactor; a second pulse on alternate
leg returns contactor to original state
• 2-wire control is the choice for single-output
automatic operation or for operation from
single-pole devices
―latches contactor into position when voltage is applied to input terminals (coil is
removed from circuit while control voltage is continuously supplied); disengages
latch and returns contactor to original state when control voltage is removed.
