A separable circuit breaker includes a separate trip apparatus portion, having a trip apparatus and a trip apparatus container, and a switching apparatus portion having a switching apparatus and a switching apparatus container. The switching apparatus and trip apparatus are connectable by connection terminals in a lower part of the respective containers. The trip apparatus portion also includes a trip apparatus cover connected to an upper portion of the trip portion container and an assistant cover rotatably connected to an upper portion of the trip apparatus cover. The assistant cover allows access to the trip apparatus. The trip appartus includes a bimetal element and an armature. The switching apparatus portion includes a crossbar and a handle. The crossbar is connected and engaged with the armature according to deformation of the bimetal element such that current flow through the circuit breaker can be opened by rotation of the crossbar when an overcurrent exists. The handle can close the circuit after it has been opened by the overcurrent condition. |
