Product details

Active production — what that means for a BOM line

The 3RA2323-8XB30-1BB4: The AC-3e maximum switching frequency is 1,000 operations per hour, which sets the duty cycle ceiling for frequent jogging or reversing applications.

Mounting and panel fit — S0 footprint on DIN rail

Size S0 means the assembly fits the standard 35 mm DIN rail via screw and snap-on mounting. Dimensions are 90 mm wide, 101 mm high, and 97 mm deep — the depth is the key dimension for enclosure depth clearance. Clearance distances around the assembly are 6 mm upwards, forwards, downwards, and to the side, with 0 mm backwards — the back can sit flush against the mounting plate.

Terminal wiring and coil voltage

Coil voltage is 24 VDC — confirm the control transformer or DC supply matches before wiring. Two instantaneous auxiliary contacts are built in, one per direction of rotation. Mechanical life is rated at 10 million operations typical, which sets the maintenance interval for high-cycle reversing applications.

Shock and vibration — what the g-ratings mean

The assembly is rated for shock resistance at 11.8 g / 5 ms and 7.4 g / 10 ms under AC conditions, and 15 g / 5 ms and 10 g / 10 ms under DC. These values define the withstand capability during transport or in-machine vibration events — relevant for panel builders shipping assembled cabinets or mounting on high-vibration equipment.
