Product details

S0 reversing assembly with two 3RT2025 contactors

The 3RA2325-8XB30-2FB4: The 24 VDC coil includes a built-in diode combination surge suppressor, so no external suppression module is needed across the coil terminals.

Mounting and panel fit

Clearance requirements: 6 mm upwards, forwards, and sideways, 0 mm backwards.

Termination and wiring

The magnet coil also terminates with spring-type terminals, consistent with the main circuit approach for tool-less wiring across the assembly.

Duty ratings across voltages

Mechanical life is 10 million operating cycles typical for the contactor size, with shock resistance of 11.8g / 5 ms (AC) and 15g / 5 ms (DC).

Environmental and compliance

Operating temperature range -25 to +60 °C, storage -55 to +80 °C.

Frequently asked questions

What is the closest functional second-source for 3RA2325-8XB30-2FB4?

The assembly is built around two 3RT2025-2FB40 contactors in a mechanically interlocked S0 frame — a panel specified around a different PLC or motor starter platform would require rewiring and a different mounting footprint.

What compliance documentation does Siemens provide for 3RA2325-8XB30-2FB4?

The SIRIUS series typically carries UL, CSA, and CE certifications — confirm specific project requirements at RFQ.
