Product details

Switching duty and mechanical endurance

The 3RT2025-2AN24: Rated for 1000 operating cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty, with AC-4 limited to 300 cycles/h — the AC-4 limit reflects the higher electrical wear from inching and plugging applications. Arcing time is specified at 4 to 16 ms (and a tighter 10 to 10 ms band in one test condition), which governs the minimum off-time between switching events and the coordination with upstream short-circuit protection.

Listed as current production — the 3RT2025-2AN24 is an active SIRIUS catalog item, not a phase-out or last-time-buy part.

Frequently asked questions

What compliance documentation does Siemens provide for 3RT2025-2AN24?

As a SIRIUS product, the 3RT2025-2AN24 carries the standard Siemens declarations of conformity for the Low Voltage Directive and relevant harmonized standards; RoHS and REACH compliance documentation is available on request.

What is the closest alternative to 3RT2025-2AN24 in the SIRIUS contactor family?

The 3RT2025-2AN24 is a Size S0 contactor with spring-type terminals. The closest functional alternative within the same frame size would be a screw-terminal variant (3RT2025-1AN24) — same coil voltage, same pole count, same switching ratings, but with screw clamps instead of spring terminals.
