There is provided an electromagnetic contactor that ensures appropriately preventing a foreign matter from invading an auxiliary contact mechanism housing chamber from a main contact mechanism housing chamber via a through-hole on a partition wall; and a foreign matter from invading the main contact mechanism housing chamber from the auxiliary contact mechanism housing chamber via the through-hole on the partition wall. With an electromagnetic contactor (1), a main contact mechanism housing chamber (A) and an auxiliary contact mechanism housing chamber (B) are partitioned by a partition wall (10). The partition wall (10) has a through-hole (10a) through which a coupling shaft (34) is inserted. A foreign matter invasion prevention mechanism (60) is provided at a peripheral area of the through-hole (10a).

An electromagnetic relay includes: a fixed terminal including a fixed terminal main body extending in a first direction, a fixed terminal arm portion, and two fixed contacts; a movable spring including two movable contacts, and extending in a second direction; a backstop; and a fixed terminal retainer. One of the fixed terminal main body and the fixed terminal arm portion is a first side terminal portion facing in the second direction, and the other is a second side terminal portion curving from a first edge of the first side terminal portion in a direction opposite to the second direction. A leg portion of the backstop is provided away from the first side terminal portion in the direction opposite to the second direction, and is provided between the two movable contacts on a projection plane with a perpendicular extending in the second direction when viewed from the first direction.

Provided is a multi-pole molded case circuit breaker (MCCB) with an insulation barrier for a rotary pin, in which an insulation barrier is provided in a rotary pin for inter-phase power transmission to prevent dielectric breakdown. The multi-pole MCCB includes a shaft assembly having a movable contactor and having a plurality of rotary pin holes formed in a penetrating manner, a base assembly to which the shaft assembly is rotatably accommodated to be coupled, a switching mechanism coupled to an upper portion of the base assembly and rotating the shaft assembly, a plurality of rotary pins coupled to the plurality of rotary pin holes in a penetrating manner, and an insulation barrier formed of an insulating material and covering the plurality of rotary pins.
