Description
 

The Macromatic CUH05A2BH is a current sensing relay. This encapsulated relay has an input voltage of 120V AC. It checks for under current faults and has an output of 10A SPDT. It monitors AC current, with an adjustable range of 0.5-5A and a trip time delay of 0.5-50 seconds. There is a 5 second sensing time delay on startup. The integrated current transformer promotes easy access and greater sensitivity. The encapsulated casing makes it ideal for use in harsh conditions. Note: Image is an approximation. Actual part may differ.

Once the input voltage is introduced and the startup time delay has passed, the relay starts monitoring for faults. For an undercurrent condition, the current needs to go below the set Fault Trip Current for a longer period than the adjusted time delay. The relay energizes after the time delay and will de-energize once the current goes back above the reset level. The CUH05A2BH includes an LED indicator which glows red to show if an undercurrent is detected. Has pilot duty rating. Useful applications include process control, monitoring for locked rotor or load loss, and open heater or lamp.
