Rated for a 24 V control circuit drawing 1 A, the relay also handles auxiliary switching at 120 V 3 A and 230 V 2 A. The main circuit uses screw-type terminals accepting 2x (0.5...2.5 mm²) solid or 2x (0.75...25 mm²) stranded; the auxiliary and control circuit uses Cage Clamp terminals for 2x (0.5...1.5 mm²) finely stranded with ferrule. The mounting position allows a vertical surface with ±135° rotation and ±45° tilt front/back, giving flexibility in crowded cabinets. Surge voltage resistance rated at 6 kV ensures the relay withstands transient overvoltages common in industrial environments, reducing the risk of insulation breakdown on the control circuit. Shock resistance of 8g / 10 ms confirms it can handle vibration and mechanical shock typical on conveyor drives and pump skids without false trips. Mounts directly onto a contactor — no separate bracket needed. The S2 frame size is the standard footprint for this current range. Main circuit screw terminals accept AWG 2x (18...3) solid or 1x (18...1). Auxiliary Cage Clamp terminals accept AWG 2x (20...14). Strip length for the Cage Clamp is not stated but standard for the terminal type is 8–10 mm. ## Compliance & Approvals Carries ATEX protection type DMT 98 ATEX G 001 for use in potentially explosive gas atmospheres. Substance prohibitance date 07/01/2006 aligns with RoHS compliance scope. Operating temperature range -20 to +70 °C; storage and transport -55 to +80 °C. Relative humidity during operation up to 100 % — suitable for high-humidity environments like washdown areas.","metaTitle":"Siemens 3RU1136-1KD0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens SIRIUS 3RU1136-1KD0 thermal overload relay, Class 10, 24V 1A, IP20, screw-type main terminals.
