It ships with two 3RT2024-1BB40 contactors inside the assembly, saving panel wiring time versus building the reversing pair from loose parts. Rated at 5.5 kW at 400 V in AC-3 duty (the standard motor-switching category per IEC 60947-4-1), it handles reversing applications for pumps, conveyors, fans, and compressors up to that load. The 24 VDC coil voltage suits modern PLC-driven control systems without an intermediate relay. The size S0 footprint (101 mm high, 90 mm wide, 107 mm deep) fits alongside other SIRIUS S0 components on the same rail. Clearance requirements are 6 mm upwards, forwards, and downwards, with 0 mm needed backwards — tight panel layouts are feasible. Main circuit and coil connections use screw-type terminals. Solid conductors from 1 mm² to 10 mm² are accepted (2x 1...2.5 mm² and 2x 2.5...10 mm² per clamp), covering typical motor feeder and control wiring. For a 480 V supply the assembly is rated 11 A AC-3, and at 690 V it delivers 7.5 kW. Horsepower equivalents are 3 hp at 230 V, 7.5 hp at 480 V, and 10 hp at 600 V. Maximum switching frequency is 1 000 operations per hour under AC-3 or AC-3e duty — adequate for frequent reversing cycles on a conveyor or indexing table, but not for high-speed jogging applications. The assembly withstands shock: 11.8 g / 5 ms and 7.4 g / 10 ms on AC, 15 g / 5 ms and 10 g / 10 ms on DC — suitable for installation on machinery with vibration.","metaTitle":"Siemens 3RA2324-8XB30-1BB4 SIRIUS Reversing Contactor Assemb","metaDescription":"Siemens SIRIUS 3RA2324-8XB30-1BB4 reversing contactor assembly, size S0, 5.5 kW at 400 V AC-3, 24 VDC coil.
