The relay's auxiliary contacts are rated across multiple control voltages: 3 A at 120 V AC, 2 A at 230 V AC, 1 A at 400 V AC, and 1 A at 24 V DC. That covers most PLC input and contactor coil circuits found in a standard panel. The relay mounts directly onto the contactor — no DIN rail required. Clearances around the unit: 0 mm upwards, forwards, backwards, and downwards; only 6 mm needed at the sides. That means it can be packed tight against adjacent devices in a multi-contactor motor starter group, saving rail space. This accommodates panel layouts where the contactor bank is rotated or angled for cable entry. Main circuit terminals accept stranded wire from 0.75 to 35 mm² (or 2× 0.75 to 25 mm²), and solid wire from 0.5 to 2.5 mm² (2×). AWG equivalents: main 2× 18 to 3, or 1× 18 to 1; aux 2× 20 to 16 or 2× 18 to 14. Screw-type terminals throughout — no spring-cage on this variant.","metaTitle":"Siemens 3RU1136-4EB0-ZX95 SIRIUS Thermal Overload Relay, CLA","metaDescription":"Siemens SIRIUS thermal overload relay 3RU1136-4EB0-ZX95, size S2, CLASS 10 trip, ATEX certified, screw terminals, IP20 front.
