The size S00 frame measures 45 mm wide, 70 mm high, and 121 mm deep — fits in compact control cabinets where every millimeter counts. Mounting position is flexible: +/-180° rotation on a vertical surface, and can be tilted forward/backward by +/-22.5°. Clearance requirements: 10 mm upward/downward/forward, 6 mm at the side. ## Rated currents for load matching Rated operational currents vary by voltage: 10 A at 24 V, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 6 A at 230 V, 3 A at 400 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V. This lets you match the contactor to the control voltage in your circuit. The 4 instantaneous contacts switch signals without delay — arcing time is 10 to 15 ms, and mechanical life is 10 million operations typical. ## Environmental and compliance Operates from -25 °C to +60 °C, stores from -55 °C to +80 °C. Pollution degree 3 (industrial environment). The brand provides RoHS compliance documentation (substance prohibitance date 10/01/2009).","metaTitle":"Siemens 3RH2244-2AP00-ZX95 SIRIUS Auxiliary Contactor, 4 NO","metaDescription":"Siemens 3RH2244-2AP00-ZX95 SIRIUS auxiliary contactor, size S00, 4 instantaneous contacts, rated 10 A at 24 V.
