SIRIUS S0 power contactor — panel fit and switching duty
The 3RT2025-1AC20-ZX95: Rated for 1,000 switching cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty, and 300 cycles per hour in AC-4 — the AC-4 figure governs applications with frequent inching or plugging. Motor rating at 230 V is 3 hp, making this contactor a fit for small to medium motor loads in panel builds.
Mounting flexibility and clearance envelope
Dimensions are 85 mm high, 45 mm wide, and 97 mm deep — the S0 footprint fits standard panel layouts with side clearance of 6 mm and vertical clearance of 10 mm (upwards, downwards, and forwards).
Mechanical endurance is 10 million switching cycles typical, which aligns with high-cycle applications like conveyor or pump control where contactor life is a BOM reliability factor.
