Cage clamp terminals on the main circuit accept 2x (0.5... 2.5 mm²) solid or 2x (0.5... 1.5 mm²) finely stranded with ferrule — no screw torque to verify, just strip to 8 mm and push in. No auxiliary contacts are built in (0 auxiliary contacts), so plan for a separate contactor block if you need status feedback. For BOM freeze or PCN watch, the SIRIUS series is a mature, widely deployed platform. If a second-source gate is needed, the closest functional peer is the 3RH6131-1BF40 — same size S00 footprint, but verify the auxiliary contact configuration and coil voltage match your circuit, as the 3RU1116-1BC1 carries zero auxiliary contacts natively. Withstands 100 % relative humidity during operation. Shock rated at 8g for 10 ms. ATEX protection type DMT 98 ATEX G 001 is listed, indicating suitability for potentially explosive gas atmospheres when installed per the associated system certificate. Power dissipation at AC in hot operating state is 5.7 W total, 1.9 W per pole — factor this into enclosure thermal calculations. Dimensions: 45 mm wide, 92 mm high, 78 mm deep. Stand-alone installation with no minimum clearance required upwards, forwards, backwards, or downwards. Side clearance is 6 mm. The size S00 form factor matches the standard Siemens SIRIUS contactor footprint for direct coupling.","metaTitle":"Siemens 3RU1116-1BC1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1116-1BC1 SIRIUS thermal overload relay, CLASS 10 trip, size S00, 690 V max, IP20 front.

This part is sourced to order against a quote; availability and current pricing are confirmed at quote time."},{"question":"When sourcing 3RU1116-1BC1, what's the closest functional second-source — 3RH6131-1BF40?","answer":"The 3RH6131-1BF40 is a size S00 peer from the same SIRIUS family, but the 3RU1116-1BC1 carries zero auxiliary contacts natively. Verify the auxiliary contact configuration and coil voltage of the 3RH6131-1BF40 match your circuit before substituting."},{"question":"What is 3RU1116-1BC1's listed depth (78 mm) on this component line?","answer":"The depth is 78 mm. Combined with a width of 45 mm and height of 92 mm, it fits the standard SIRIUS S00 contactor footprint."},{"question":"What is 3RU1116-1BC1's listed solid (2x (0.5... 2.5 mm²)) on this component line?","answer":"The cage clamp terminals accept 2x (0.5... 2.5 mm²) solid conductors, or 2x (0.5... 1.5 mm²) finely stranded with core end processing."},{"question":"Will 3RU1116-1BC1 drop into a panel that was specified around 3RH6131-1BF40 without rewiring?","answer":"Both are size S00 and share the same mounting footprint and terminal pitch, so mechanical fit is identical.
