Product details

The coil is 24 VDC rated, drawing 10 A at the rated value.

The contactor is designed for standing installation on a horizontal mounting surface. That 6 mm side gap is tight — adjacent devices can sit close, but verify the arc-chamber vent path isn't blocked. The 97 mm depth means it projects 97 mm from the DIN rail front face, so the enclosure depth needs to clear that plus wiring space. No derating curve is listed here, but the 60 °C ceiling is typical for a panel-mounted contactor — keep the ambient inside the enclosure below that.

Switching performance and lifecycle

Electrical switching frequency depends on duty: AC-1, AC-2, AC-3, and AC-3e all allow up to 1,000 operating cycles per hour. The heavier AC-4 duty (frequent inching or plugging) is limited to 300 cycles per hour. Arcing time is 10 to 10 ms — a tight window that suggests consistent arc quenching.

Frequently asked questions

Is 3RT2025-1AB00-1AA0-ZX95 the same as 3RT2025-1AB00?

The base order code 3RT2025-1AB00 identifies a standard SIRIUS contactor without the -1AA0-ZX95 suffix. The -1AA0-ZX95 suffix typically indicates a special version or customer-specific variant — the ratings and footprint are the same, but verify the exact variant requirements with the BOM before substituting.
