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.","metaTitle":"Siemens 3RU2116-0KB0-ZX95 SIRIUS Thermal Overload Relay, S00","metaDescription":"Siemens SIRIUS 3RU2116-0KB0-ZX95 thermal overload relay, size S00, Class 10 trip, 690 V rated, for contactor mounting.
