Rated for AC-3 duty up to 690 V and fitted with cage clamp terminals on the main circuit (2× 0.5–2.5 mm² solid or 2× 0.5–1.5 mm² finely stranded with ferrule), it mounts standalone or on a contactor in the S00 family without needing extra DIN-rail hardware. At 45 mm wide × 92 mm tall × 78 mm deep, this S00 overload relay occupies a single 45 mm slot on a DIN rail or contactor base. This means you can pack relays tightly in a row without derating, as long as the side gap to adjacent components or enclosure walls is at least 6 mm. Operating temperature spans -20 to +70 °C; storage and transport extend from -55 to +80 °C. The ATEX approval (DMT 98 ATEX G 001) covers use in potentially explosive gas atmospheres — check the specific zone and gas-group compatibility against your installation's classification. This relay ships with zero factory-fitted auxiliary contacts (: 0). The auxiliary contact block is ordered separately and snaps onto the front. When sizing the control circuit, use these make/break capacities: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V — all at the respective AC voltage. For DC control, the 110/125 V rating is 0.22 A and 220 V is 0.11 A. ## Power dissipation and wiring At rated AC current in hot operating state, the relay dissipates 5.7 W total (1.9 W per pole). Main circuit terminals accept 2× 0.5–2.5 mm² solid or 2× 0.5–1.5 mm² finely stranded with ferrule (AWG 24–14).","metaTitle":"Siemens 3RU1116-0KC1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1116-0KC1 SIRIUS thermal overload relay, CLASS 10, S00 frame, 690 V max, cage clamp terminals.
