A relay device includes a positive terminal, a negative terminal spaced from the positive terminal, and a movable terminal that moves between a connection position and a distant position, the connection position being a position at which the movable terminal connects the positive terminal to the negative terminal, the distant position being a position at which the movable terminal is distant from the positive terminal and the negative terminal. The movable terminal includes a first contact portion connected to the positive terminal, a first portion extending away from the first contact portion, a second contact portion connected to the negative terminal, a second portion extending away from the second contact portion, and a connecting portion connecting the first portion to the second portion. The first portion and the second portion are disposed to be opposed to each other.

A contactor includes a pair of fixed contacts, a movable contact element configured to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, a movable shaft configured to move in an axial direction as to cause the movable contact element to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, and a partition-wall component disposed opposite to the pair of fixed contacts with respect to the movable contact element. The first partition-wall component includes a partition wall provided around the movable shaft. The first partition wall is configured to move synchronously with at least one of the movable contact element and the movable shaft.

A power distribution system includes an electrical contactor arrangement. The electrical contactor arrangement includes a first contactor post, a first contactor lead, and a second contactor lead. The first contactor post extends from a first bus bar. The first contactor lead extends from the first contactor post. The first contactor lead is at least partially received within a contactor housing. The second contactor lead is spaced apart from the first contactor lead and extends from the first contactor post. The second contactor lead is at least partially received within the contactor housing.

Disclosed embodiments relate to an auxiliary relay of an electronic contactor. In some embodiments, an auxiliary relay has its conducting state controlled by a plurality of lead switches, in a non-exposed state of contact parts to the outside. This may prevent dust or foreign materials from clinging to the contact parts.

An electromagnetic actuator having a permanent magnet coupled to an armature of the electromagnetic actuator is provided. The electromagnetic actuator includes a housing, a pole piece arranged within the housing and secured by an end plate, and an armature assembly having an armature and a permanent magnet coupled to the armature. The armature is movable between a first position and a second position. The electromagnetic actuator further includes a wire coil positioned around the armature assembly and arranged within the housing. An actuation position of the armature between the first position and the second position is proportional to a magnitude of current applied to the wire coil.
