Product details

For motor loads, it is rated 4.5 kW at 400 V in AC-2 duty and 5.5 kW at 690 V. Auxiliary contact ratings are voltage-dependent: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V — the lower current at higher DC voltages reflects the arc-extinction limit of the contact gap.

The contactor occupies a 45 mm wide DIN-rail footprint, 85 mm tall, 91 mm deep. Main-circuit screw terminals accept 2x (1 to 2.5 mm²) stranded or 2x (2.5 to 6 mm²) solid, with a maximum of 2x 10 mm². Auxiliary terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, max 2x (0.75 to 4 mm²). AWG equivalents for main contacts are 2x (16 to 12) and 2x (14 to 10), with a single 8 AWG maximum. Short-circuit coordination: with type 2 coordination, use a gL/gG fuse rated 25 A; with type 1 coordination, the fuse can be 63 A.

Frequently asked questions

What are the main contact ratings for this contactor?

Three normally-open main contacts. Motor ratings: 4.5 kW at 400 V AC-2, 5.5 kW at 690 V. AC-4 switching current is 8.5 A at 400 V.

Will 3RT1023-1AP00-1AA0 drop into a panel specified for 3RT1023-1AL20 without rewiring?

Both are S0-frame SIRIUS contactors with the same 45 mm width and DIN-rail mounting, so the mechanical footprint is identical. The key difference is the coil voltage — 3RT1023-1AP00-1AA0 uses a 230 V 50 Hz coil, while 3RT1023-1AL20 uses a different coil voltage. The terminal layout and wire ranges are the same, so a panel designed for the 1AL20 will accept the 1AP00-1AA0 without rewiring, provided the coil supply matches.

Where can I buy 3RT1023-1AP00-1AA0 and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
