At 230 V it's rated 3 hp (cites:), so it handles fractional-to-medium motor sizes in a compact 45 mm wide package (cites:). That's the standard rail profile in any EU or export panel, so it drops into existing layouts without adapter plates. Standing position on a horizontal surface is the specified orientation (cites:). Wire terminations accept solid or stranded conductors from 1 to 10 mm² (cites:, cites:), and the main contacts can take two conductors per terminal in the 0.5 to 2.5 mm² range (cites:). That covers most panel wiring from control circuits to motor feeds. Coil connections are screw-type terminals (cites:) — no push-in or spring-cage on this variant, so factor in screwdriver access during wiring. ## Switching rates and mechanical life Rated for up to 1,000 switching cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty (cites:, cites:, cites:, cites:). That's typical for a general-purpose contactor in conveyor, pump, or fan cycling. For AC-4 duty — plugging or inching — the rate drops to 300 cycles per hour (cites:), reflecting the heavier arc wear from reversing or jogging under load. Mechanical life is quoted at 10 million operations typical (cites:), so it'll outlast most machines it's wired into. ## DC switching capability This contactor also handles DC loads, which matters for battery-backed or rectified circuits. Rated 10 A at 24 V DC, 2 A at 48 V and 60 V DC, 1 A at 110 V DC, and 0.3 A at 230 V DC (cites:, cites:, cites:, cites:, cites:). At 440 V DC it's rated 0.6 A (cites:). These are the DC-1 / DC-3 style values — resistive and lightly inductive loads. If you're switching DC motor fields or solenoid valves, these numbers govern the contactor's life, not the AC ratings. ## Environmental limits and clearances That's standard for a panel-mounted contactor — no special cooling needed in a ventilated enclosure, but keep it out of direct steam or oven exhaust. That's tighter than some older contactor families, so it packs into a smaller backpanel footprint without derating.","metaTitle":"Siemens SIRIUS 3RT2025-1AB00-1HA1-ZX95 Power Contactor, Size","metaDescription":"Siemens SIRIUS 3RT2025-1AB00-1HA1-ZX95 power contactor, Size S0, rated 14 A at 480 V AC-3, 3 hp at 230 V.
