A circuit breaker includes a shielding component having an external portion which defines a space external to the circuit breaker housing and covers a vent in the circuit breaker housing to direct gasses and debris from the vent to an outlet. The external portion also prevents insertion of the circuit breaker into a breaker box closer than the distances defining the space. This can have the advantage of preventing arcing from the breaker contacts to the breaker box. The external portion may also prevent insertion of the circuit breaker into a breaker box such that a vent in the circuit breaker housing is blocked. In some implementations, the shielding component contains an internal portion which extends into the circuit breaker housing and is disposed to impede debris generated by contact arcing, or other debris, from entering the mechanism of the circuit breaker. |

An electrical contactor with high DC and AC interrupt capability is disclosed. The invention is intended for applications where load break capability is only required under abnormal operating conditions. Under overload conditions, an alternate path is automatically provided through a sacrificial fuse to divert current from opening, or open and arcing, contacts such that the fuse interrupts the fault current and not the contacts. The current rating of the sacrificial fuse may be orders of magnitude less than the normal carry current of the contactor. The contactor provides a one-time load break function that is renewable by the replacement of a fuse. |

The base has a conductive member depressed by the press element and a connecting section extended upwards. The base also includes a first contact, and a second contact extended from the connecting section and located above the first contact. The conductive member is swung during up and down movement of the press element to connect with the first or the second contact. The connecting section has an isolation portion jutting sideward between the first and second contacts to prevent generation of a conductive layer caused by connection of the conductive member with the first and second contacts on the connecting section.

A noise decreasing type electromagnetic switch includes a buffer disposed between a stationary core and a contact spring to electrically support a shaft and the stationary core. The buffer includes a buffering space therein. Accordingly, impact caused at the stationary core and the shaft can be effectively absorbed even by the buffering space as well as an elastic force of the buffer. The buffer is inserted in the stationary core for coupling so as to be prevented from being separated during operations, resulting in maintaining long-term durability. Also, the buffer may support the stationary core and a metal plate, whereby an assembly process can be simplified. |
