Product details

SIRIUS S0 power contactor — 45 mm wide, DIN-rail snap-on

The 3RT2025-1AR60: It carries an integrated auxiliary switch and is rated for up to 1,000 switching cycles per hour in AC-3 and AC-3e duty, with a reduced 300 cycles per hour in AC-4 duty for demanding motor braking or reversing applications.

Thermal and clearance envelope

Minimum clearance distances: 10 mm upward, downward, and forward, 6 mm at the sides — these are the air-gap requirements for heat dissipation and arc containment. Arcing time is 4 to 16 ms at AC, with a typical value of 10 ms — this informs coordination with upstream overcurrent devices.

Coil power draw and mechanical life

Coil power consumption is 0.25 VA at 50 Hz and 0.28 VA at 60 Hz — low enough for direct PLC output drive in most panels without an interposing relay.

Frequently asked questions

What is the 3RT2025-1AR60 used for?

The 1,000 cycles/hour AC-3 rating suits standard motor starting; the 300 cycles/hour AC-4 rating covers reversing or plugging duty.
