Replacement Contact Kit

The SIEMENS 75JG14 kit provides a single replacement contact for maintaining compatible Siemens contactors. It is designed for industrial electrical control panels requiring NEMA Size 4 components. Maintenance technicians use it to restore reliable switching function in automation systems.

Sustained load behaviour

The kit includes movable contacts, springs and stationary contacts engineered for the mechanical demands of industrial contactor operation. These components work together to maintain consistent electrical continuity during repeated switching cycles. The assembly supports the contactor's rated duty cycle without degradation.

Thermals noise and power

As a passive contact assembly, the kit generates no operational noise and draws no power itself. Contact resistance remains stable at normal operating temperatures within the enclosure. Proper installation ensures heat dissipation matches the original contactor design specifications.

Questions about this item

Does the 75JG14 contact kit generate noticeable heat or noise during continuous operation?

The kit consists of passive metal contacts and springs with no moving or powered parts, so it produces no heat or noise once installed in the contactor.

Which Siemens contactor series and NEMA size must I already own for the 75JG14 kit to fit?

It is designed for Siemens Multiple Class contactors rated at NEMA Size 4.

Will the 75JG14 contacts work reliably alongside the older coil and auxiliary blocks already in my NEMA Size 4 contactor?

Yes, the movable and stationary contacts in the kit are direct replacements that mate with the existing coil mechanism and auxiliary components without modification.
