The auxiliary contact is integrated and carries a note \"for message 'Tripped'\" — that normally-closed 95-96 contact opens on overload, feeding a PLC or indicator directly. No separate aux block needed. The switching capacity across the aux contact covers 2 A at 24 V and 3 A at 120 V, enough for a 24 VDC PLC input or a 120 V alarm lamp. Spring-loaded terminals accept 2× 0.5 to 2.5 mm² solid or stranded, so the wireman's standard 1.5 mm² motor lead fits without ferrules. Temperature compensation is active from -40 to +60 °C, meaning the trip curve doesn't drift when the relay sits next to a warm contactor in a non-ventilated enclosure. Fastening method is contactor mounting — it clips onto the 3RT2 contactor's front face, not a DIN rail. The relay measures 45 mm wide, 87 mm tall, 70 mm deep, so it adds about 70 mm of depth to the contactor assembly. Any mounting position is allowed, so vertical or horizontal orientation in the panel is fine. The screwdriver slot for the terminal screws takes a 3 mm diameter shaft, 3.0 × 0.5 mm tip — a standard PZ1 or slotted 3 mm works.","metaTitle":"Siemens 3RU2116-1DC0 SIRIUS thermal overload relay, CLASS 10","metaDescription":"Siemens 3RU2116-1DC0 SIRIUS thermal overload relay, CLASS 10 trip, S00 size, 690 V rated, spring-loaded terminals.
