The contactor mounts via screw or snap-on to a DIN rail, with a footprint of 90 mm wide by 57.5 mm high and 114 mm deep — a compact S00 frame that fits tightly into crowded enclosures. The 5 NO instantaneous contacts (no leading, lagging, or make-before-break) are rated for AC-15 and DC-13 auxiliary loads typical of contactor coils, solenoid valves, and indicator lamps. The 10 A at 24 V rating covers most PLC output and relay coil switching; at 230 V AC it's still good for 6 A, and at 400 V AC it handles 3 A. That means it can switch a small contactor coil or a bank of pilot lights without derating concerns. That gives the panel builder room to orient the contactor for wire routing or access. Strip length and ferrule sizing follow standard SIRIUS practice.","metaTitle":"Siemens 3RH1453-1AP00-4AA0 SIRIUS Auxiliary Contactor, 5 NO","metaDescription":"Siemens SIRIUS 3RH1453-1AP00-4AA0 auxiliary contactor, size S00, 5 NO instantaneous contacts, IP20 front, screw and snap-on mounting, rated 10 A at 24 V.
