CR Magnetics CR7310-EH-120-.11-X-CD-NPN-I Sensing Relay, 120 VAC

CR Magnetics, CR7310-EH-120-.11-X-CD-NPN-I, CR7310 Ground Fault Current Sensing Relay

The CR7310 series, Ground Fault Sensor provides a reliable and cost-effective method for sensing ground faults. The current-carrying wires are routed through the opening extending from the top of the case. When the ground current reaches the level set by the trip point adjustment, the relay trips, illuminates the tripped LED, and provides an output signal. A precision voltage reference circuit ensures a highly repeatable trip point. The Sensor is rated as a Class 1 device.

Features:

• Variable trip point and time delay
• Monitors currents from 10 mAAC to 100AAC
• Electrical isolation between circuits
• Output relay rated up to 20 Amp
• LED trip status indicator
• Dead band prevents relay chatter

Applications:

• Monitor electrical heater elements
• Sense motor over/under loads
• Detect lamp burn-out
• Indicate phase loss
