PURPOSE: A circuit breaker with a trip notifying unit is provided to enable a user to grasp the cause of a trip by classifying a circuit breaker tip alarm contact. CONSTITUTION: A magnetic trip device trips a relay when a fault current is generated. A low voltage trip device performs a low voltage tip operation if the control power falls below a preset voltage. A first switch outputs a relay trip operation to the outside. A second switch outputs the low voltage trip operation to the outside. |
