The present disclosure relates to a frame of an electromagnetic contactor, and more specifically, to an electromagnetic contactor having excellent coupling force between an arc box and a frame. The electromagnetic contactor, comprises: a lower frame; an upper frame coupled to the upper portion of the lower frame; and an arc cover coupled to the upper portion of the upper frame, wherein a first coupling part is protrudingly formed on one surface of the lower frame, a second coupling part, connected to the first coupling part, is protrudingly formed on one surface of the upper frame, and a third coupling part, connected to the second coupling part, is protrudingly formed on one surface of the arc cover, wherein the fastening member is fastened by connecting the first coupling part, the second coupling part and the third coupling part.

An intelligent relay package is disclosed, comprising: a relay configured to control delivery of current to a load, wherein the relay comprises a set of contacts; and a set of rigid busbars coupled to the set of contacts of the relay, wherein the set of rigid busbars is configured to transfer heat generated due to contact resistance away from the set of contacts and to a set of wires coupled to the set of rigid busbars, wherein the intelligent relay package is sized to fit within a single slot of a load tray.

A relay, includes a housing and multiple contact modules. An interior of the housing has an accommodation space, and each contact module includes a terminal assembly, a movable contact plate, and a drive assembly. The terminal assembly includes two terminals spaced apart and disposed on the housing. The terminal at least partially extends into the accommodation space to form a static contact. The movable contact plate is movably disposed in the accommodation space, and is configured to contact two static contacts to conduct the two terminals. The drive assembly includes a drive shaft and a drive unit that drives the drive shaft. The drive shaft is connected to the movable contact plate, and the drive unit is configured to drive the movable contact plate via the drive shaft. Multiple drive shafts corresponding to the multiple contact modules are disposed coaxially, and are relatively movable in their axial direction.

An electromagnetic relay includes a case, a contact device, and an electromagnet device. The contact device includes a fixed contact and a movable contact piece including a movable contact. The electromagnet device is configured to drive the contact device. The electromagnet device is housed in the case. The electromagnet device includes a yoke. The yoke includes an extending portion extending to outside the case. The yoke is secured to the case via the extending portion.
