Current Sensing Relays

Current Sensing Relays

Select from a wide variety of AC & DC Current Sensing Relays. These relays protect sensitive and expensive equipment against over- or under-current conditions. Choose mounting configuration and then select from a variety of functions, time delay settings, and output configurations.

Protect Equipment and Critical Processes

Current monitors relays  (sometimes referred to as current monitor relays) detect current faults in critical environments.  These relays are often used to sequence operations. They can monitor ventilation and HVAC systems, locked rotor or load loss conditions, no-load conditions, conveyor jam-ups, machine tool wear, heater or lamp loads, and other critical applications.

plug-in

Plug-In

COKP Series use 8 pin octal sockets. These relays monitor AC over-current within three separate adjustable current monitoring ranges. CAP Series use 11 pin sockets. These relays monitor AC and DC over-current within three built-in current ranges.

Encapsulated

CAH, COH and CUH Series offer protection in harsh environments. These relays monitor AC over-current or under-current within three adjustable current ranges. They mount and connect easily with two screws and quick-connect termination.
