Description

The Macromatic CUH05A2BE 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 2 second sensing time delay on startup. The built-in current transformer provides easy access and greater sensitivity. The encapsulated housing is ideal for use in harsher environments. 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 situation, the current needs to go under the set Fault Trip Current for longer than the time delay. The relay energizes after the time delay and will de-energize once the current goes over the reset level. The CUH05A2BE has an LED indicator which glows red to show if an undercurrent fault is detected. Has pilot duty rating. Applications such as process control, monitoring for locked rotor or load loss, and open heater or lamp are all suited for this type of relay.
