Product details

S0 frame, 45 mm on the rail — what that means for your panel

The 3RT2025-1AB00-1AA0-ZW96: That footprint is the standard S0 envelope; it eats one 45 mm DIN module and needs 97 mm of depth behind the panel door for the arc chamber and terminals. The standing position on a horizontal surface is the specified orientation — mounting it sideways or inverted shifts the arc-quenching geometry and the thermal path. Wire range accepts solid or stranded from 1 mm² up to 10 mm² — that covers 18 AWG through 8 AWG.

Rated current at 480 V — the motor load number that matters

At 480 V the main contacts are rated 14 A, and the contactor carries a 3 hp motor load rating at 230 V. Those are the numbers to check against your motor nameplate — the 14 A at 480 V is the continuous current ceiling in AC-3 duty, not a startup surge figure. If you're using the aux for a PLC input or a holding circuit, the 24 V / 10 A rating gives you headroom for inrush from a relay coil.

Clearance and temperature — the installation constraints

In a packed enclosure those numbers determine whether the contactor can breathe — less clearance traps heat and derates the current-carrying capacity. For a panel sitting in a non-conditioned plant space, the -25 °C floor means it starts reliably in a cold warehouse; the +60 °C ceiling limits how close it can sit above a drive or transformer without forced air.

Sourcing and lifecycle — where this part sits today

The 45 mm S0 footprint and screw-terminal wiring are standard — no special tooling or adapter required.
