S0 reversing contactor assembly with spring-loaded terminals
The 3RA2325-8XB30-2AC2 is a SIRIUS reversing contactor assembly, size S0, supplied as a pre-assembled unit with two 3RT2025-2AC20 contactors and a mechanical interlock. It is designed for reversing motor loads in control panels and industrial machinery. The coil is rated 24 V AC/DC at 50/60 Hz. The main current circuit uses spring-loaded terminals, and the magnet coil connection uses spring-type terminals. This eliminates routine screw-torque checks during installation and maintenance.
Mounting and panel integration
Dimensions: 114 mm height, 90 mm width, 97 mm depth. The S0 footprint is common across the SIRIUS contactor range, so panel cutouts and busbar layouts transfer between units. Clearance distances: 6 mm upwards, 6 mm forwards, 6 mm downwards, 6 mm at the side, 0 mm backwards. These are the minimum air gaps to adjacent metalwork for heat dissipation and arc flash containment.
