It ships with two 3RT2026-1BB40 contactors inside, so you get the reversing pair in a single S0 frame footprint, screw-terminated, with a 24 VDC coil. Rated 11 kW at 400 V AC-3 (21 A at 480 V, 22 A at 600 V), it handles reversing motor loads up to that power band. The AC-3 duty cycle is 750 operations per hour maximum, which covers frequent jogging or inching in conveyor and hoist applications. The S0 frame is 90 mm wide, 101 mm tall, 107 mm deep — fits standard panel layouts. Clearance: 6 mm upwards, forwards, downwards, and to the side; zero backwards. Wire range: solid or stranded 2x (1…2.5 mm²) and 2x (2.5…10 mm²) for the main circuit; auxiliary contacts take 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²). All terminals are screw-type — no special tooling needed.","metaTitle":"Siemens SIRIUS 3RA2326-8XB30-1BB4 Reversing Contactor Assemb","metaDescription":"Siemens SIRIUS reversing contactor assembly, 11 kW at 400 V AC-3, 24 VDC coil.
