FEATURES

• No physical connection to the AC line that is being

• Magnetically coupled by passing supply line through

• Heavy Duty Contacts

• 8-Pin, Plug-in

• Low Cost

• Easy Installation

OPERATION

The CMB Series relay is used to detect the presence of AC current. When

the monitored current exceeds the trip point for longer than 30 millisec-

onds, the internal relay energizes. When the monitored current drops

below the trip point for longer than 0.5 seconds, the internal relay

de-energizes. The Delay-on-Release is incorporated to prevent nuisance

tripping caused by momentary dips in the load line.

An External CT may be used to extend the range of the Current Monitor.
