The present disclosure relates to a molded case circuit breaker, and particularly, to a molded case circuit breaker having an enhanced arc protecting function. The molded case circuit breaker includes: a power side terminal portion provided at a front side of an enclosure and having a fixed contact arm; a finger assembly coupled to the fixed contact arm, and disposed on a front surface of the power side terminal portion; and a base bus supporter coupled to an upper surface and a lower surface of the power side terminal portion, and having a finger hole through which the finger assembly is exposed. The base bus supporter is provided with a protection unit configured to enclose the finger assembly around the finger hole.

Rotary switch (1, 101) comprising: a rotor (15, 115) supporting at least one electro-conductive rotary contact bridge (19, 119); a plurality of stationary contacts (21, 121); a housing (3, 103) accommodating the stationary contacts and the rotor. The housing comprises a plurality of sides (5, 105) extending between a top side and a bottom side. At least two of these sides (5, 105) are provided with access openings (62, 62) providing access to an associated stationary contact. These sides make an angle with each other. The housing may for example be rectangular.

A highly durable, quiet switch includes a housing, a stationary contact terminal including a fixed portion, a moving contact terminal, a moving contact unit including a body, a moving portion, and an urging member and connected to the moving contact terminal, an operating unit, a first elastic unit that comes in contact with the moving contact unit and elastically deforms when the moving portion moves away from the fixed portion, and a second elastic unit including a contact point between the moving portion and the fixed portion facing the moving portion to come in contact with the moving portion. The second elastic unit elastically deforms and electrically connects the stationary and moving contact terminals when the moving portion moves toward the fixed portion and comes in contact with the contact point.

A grounding system for a rackable circuit breaker includes a finger cluster connector connected to a grounding bus in the circuit breaker and a rail conductor mounted in a circuit breaker cradle and connected to ground potential. The finger cluster connector includes a conductor formed from a single plate of conductive material folded into a generally U-shaped body with first and second sides divided into a plurality of fingers. Distal ends of the fingers form mutually facing parallel surfaces of a constricted passage configured to make a sliding electrical contact with the rail conductor that is advanced into the constricted passage as the circuit breaker is racked into the cradle. First and second leaf springs fastened to the conductor portion are divided into a plurality of spring finger sections with spring distal ends configured to respectively press against the distal ends of respective fingers of the conductor portion.

A cover for an electric switch assembly is disclosed in the present application. The cover includes connecting features that permit connection to a housing for the switch assembly in at least two locations. A first location is defined by a cover positioned to completely enclose all electrically conductive components in the switch assembly. A second location is defined by a cover positioned to enclose a portion of electrically conductive components and to permit access to a circuit associated with an open switch in the switch assembly.
