Product details

What this mechanical connector does in the panel

The 3RA1932-2G is a mechanical interlock kit for SIRIUS contactor assemblies size S2, designed specifically for 4-pole reversing configurations with a 10 mm contactor clearance. It comprises two mechanical connectors that physically interlock one reversing combination, preventing both contactors from closing simultaneously.

Sourcing for legacy maintenance and spares

For existing installations that require the 3RA1932-2G form factor, we source this phased-out part through independent distribution channels.
