Product details

The coil is 24 VAC, 50/60 Hz, drawing 0.25 A at 50 Hz and 0.28 A at 60 Hz — a standard control voltage that matches most PLC or relay outputs in North American and European panels. The main contacts are rated for 10 A at 24 V and 230 V, and 3 A at 400 V; that tells you this is a moderate-duty contactor for smaller motors or resistive loads, not a high-current main breaker. The auxiliary switch is built in, rated 10 A at 24 V, 6 A at 60 V, 1 A at 110 V, and so on down to 0.1 A at 600 V — so it can handle pilot duty or signal feedback across a wide voltage range without an add-on block.

Physical dimensions and wiring clearances

The contactor measures 85 mm high by 60 mm wide by 97 mm deep. The screw terminals accept solid wire 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²), and stranded 1 to 10 mm². That covers most control wiring up to about 8 AWG.

Frequently asked questions

Where can I buy 3RT2327-1AH20 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at that time.

What is 3RT2327-1AH20's listed depth?

The depth is 97 mm, with a height of 85 mm and width of 60 mm.

Will 3RT2327-1AH20 drop into a panel specified around 3RT2326-1BK80 without rewiring?

Both are SIRIUS size S0 contactors sharing the same DIN-rail footprint and screw-terminal layout, so mechanical fit is the same. Verify the coil voltage — 3RT2327-1AH20 uses a 24 VAC coil — and confirm the auxiliary contact ratings match your control circuit before direct swap.
