Control Power For The Circuit Breaker​

• The circuit breaker's control circuitry needs a low voltage AC or DC power supply. This power can come from the load circuit in a fixed voltage system or from a separate supply, such as a plug-in type transformer, for a variable voltage load. See the diagralm below for examples.
• The voltage of the supply for the control circuitry must not exceed 16 Volts AC or 24 Volts DC. The current requirement for the breaker circuit is 100 milliamps when the relay is ON (Breaker is Tripped).
• More than one circuit breaker can be operated from a single power supply if the supply has a capacity of 100 milliamps per breaker connected.
• If there is no control power for the circuit breaker, the load circuit will remain closed.
