Description
 

The Macromatic CAH05A2BG is a current sensing relay. This encapsulated relay has an input voltage of 120V. It checks for either over or undercurrent errors and has an output of 10A SPDT. It is made for AC current, and features an adjustable range of 0.5-5A with a trip time delay of 0.5-50 seconds. There is a 4 second time delay on startup. The built-in current transformer creates better access and sensitivity, as the wire can be looped more than once. The encapsulated housing makes it perfect for use in harsher environments. Note: Image is an approximation. Actual part may differ.

The user chooses whether the relay monitors for over or under current faults with the selector switch. The relay starts monitoring for possible faults once the input voltage is introduced. In an overcurrent situation, the AC current rises above the set Fault Trip Current for longer than the adjusted time delay. The relay energizes after the time delay and stays energized until the current drops below the reset level. For an undercurrent fault, the current falls below the set Fault Trip Current for longer than the time delay. Again, the relay energizes after the time delay and de-energizes once the current rises above the reset level. The CAH05A2BG has an LED which glows red to indicate when a fault is detected. Has pilot duty rating. Common application examples include process control, monitoring for locked rotor or load loss, or open heater or lamp.
