Product details

The Siemens 3RU2116-0KC0-ZW97 is a SIRIUS thermal overload relay in size S00, CLASS 10 trip, 690 V rated, 50 to 60 Hz, contactor mounting. The auxiliary contact set is rated across multiple voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.3 A at 60 V, among others. These ratings cover both control-circuit and signal-feedback wiring — the 24 V and 120 V figures matter most for PLC inputs and relay coils in a typical panel.

The main current circuit uses spring-loaded terminals, accepting 2 × (0.5 to 2.5 mm²) solid or stranded conductors. The screwdriver shaft diameter is 3 mm with a 3.0 × 0.5 mm tip size for the auxiliary terminal screws.

Frequently asked questions

What is the closest functional second-source to 3RU2116-0KC0-ZW97?

The 3RU2116-1FC1 is a peer in the same SIRIUS size S00 family. Both are CLASS 10 thermal overload relays with the same mounting footprint and terminal style. The difference is in the auxiliary contact configuration and possibly the current setting range — verify the specific rating plate before substituting, but the mechanical fit is identical.
