Rated for Size S2 frame, it mounts directly onto the matching SIRIUS contactor via the contactor mounting fastening method — no separate DIN-rail bracket needed. The front face carries IP20 protection, safe for finger-probe access inside an enclosure. ## Terminal capacity and wiring range All terminals are screw-type, so expect a screwdriver for termination. Power dissipation per pole is 3.5 W — factor this into the enclosure thermal budget when the relay is continuously loaded at the full setting range. ## Environmental and compliance profile The relay withstands 100 % relative humidity during operation and shock up to 8g for 10 ms. Surge voltage resistance is rated at 6 kV, covering typical industrial transient conditions. Carries ATEX certification DMT 98 ATEX G 001, allowing use in potentially explosive gas atmospheres when paired with an appropriate contactor and motor. The mounting position is flexible — vertical surface with ±135° rotation and ±45° tilt front-to-back — easing panel layout constraints.","metaTitle":"Siemens 3RU1136-4AB0 SIRIUS Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1136-4AB0 SIRIUS thermal overload relay, CLASS 10 trip, Size S2, screw terminals, ATEX certified.
