Product details

The Siemens SIRIUS 3RU2116-0KB0-ZX95 is a thermal overload relay in size S00, designed for direct mounting onto a contactor in motor control circuits.

The auxiliary contact is rated 2 A at 24 V, 3 A at 120 V, and 2 A at 230 V, covering the common control voltages in North American and European panels. At 400 V the auxiliary contact is rated 1 A, and at 690 V it drops to 0.3 A — so if you're switching a higher-voltage PLC input or a remote indication lamp, verify the voltage and current fall within these curves. Mounting is via the contactor's own footprint — no separate DIN-rail bracket needed. The relay snaps onto the contactor and connects the main circuit through screw terminals accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire.

Frequently asked questions

What does the 'for message Tripped' note mean?

The note indicates that the auxiliary contact on this relay is wired to signal a 'Tripped' condition — typically a normally-closed contact that opens when the overload relay has operated, used to trigger an alarm or stop the upstream contactor.

Will the 3RU2116-0KB0-ZX95 fit into a panel designed for a 3RV1011-1HA10?

No, the 3RV1011-1HA10 is a motor circuit protector (MCP) with a different footprint and mounting method. The 3RU2116 is a thermal overload relay designed to mount onto a contactor, not onto a DIN rail or into an MCP base. Panel wiring and layout would need to be revised.

What compliance documentation does this part carry?

The part carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance. The SIRIUS series typically carries UL, CSA, and CE approvals, though specific certifications for this variant should be confirmed from the nameplate or manufacturer's declaration.
