Rated for the Size S2 frame, this relay mounts directly to a contactor via the fastening method specified, saving DIN-rail space in the panel. The IP20 front protection allows safe operation in enclosed control cabinets where accidental finger contact is possible. ## ATEX certification and compliance documentation The 3RU1136-4DD0 carries ATEX certification (DMT 98 ATEX G 001), confirming its suitability for use in potentially explosive atmospheres — a requirement for motor protection in Zone 1 or Zone 2 gas environments. The relay meets the substance prohibitance date of 07/01/2006, aligning with RoHS compliance for the European market. ## Physical dimensions and mounting clearances The relay measures 55 mm wide, 105 mm high, and 118 mm deep. This tight clearance profile allows dense packing in the enclosure without forced air gaps.","metaTitle":"Siemens 3RU1136-4DD0 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1136-4DD0 SIRIUS thermal overload relay, CLASS 10 trip, IP20 front, ATEX certified.
