SIEMENS 75IF14 Contactor Contact Kit 1 Pole NEMA Size 3-1/2

Replacement Contact Kit

This Siemens 75IF14 kit provides the movable contacts, springs and stationary contacts required to service a single pole on NEMA Size 3-1/2 contactors. It is intended for maintenance teams restoring worn power contacts in motor starters and lighting contactors.

Fits Siemens Multiple Class Contactors

The kit matches the contact geometry of the specified NEMA size, allowing direct replacement without modifying the contactor base or wiring. It frees the operator from sourcing individual components and ensures the original contact pressure and alignment are maintained.

Sustained Load Behaviour

Under continuous duty the silver-alloy contacts resist welding and erosion, keeping voltage drop stable over repeated make-break cycles. The included springs preserve consistent closing force, preventing contact chatter that accelerates wear during prolonged operation.
