Description
 

The Macromatic CAH05A1BG is a current sensing relay. This encapsulated relay has an input voltage of 240V. It is designed to check for over or undercurrent situations 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 4 second sensing time delay on startup. The integrated current transformer makes for easy access and greater sensitivity. The encapsulated housing is made for use under harsh conditions. Note: Image is an approximation. Actual part may differ.

It is possible to choose whether the relay monitors for over or under current conditions. The relay starts monitoring for possible faults once the input voltage is introduced. For an overcurrent situation, this occurs when the AC current goes over the set Fault Trip Current for longer than the adjusted time delay. The relay energizes after the time delay and remains energized until the current goes below the reset level. For an undercurrent situation, the current needs to go below the set Fault Trip Current for longer than the time delay. Again, the relay energizes after the time delay and will de-energize once the current goes over the reset level. The CAH05A1BG has an LED which glows red to indicate when a fault is detected. Has pilot duty rating. It is ideal for applications such as process control, monitoring for locked rotor or load loss, or open heater or lamp.
