Product details

It is rated for 7.5 kW at both 500 V and 690 V, and carries an AC-4 breaking current of 12.5 A at 400 V — so it handles reversing or inching duty where the contactor breaks full motor current, not just the running load.

The S0 frame measures 45 mm wide by 85 mm high by 90 mm deep, so it fits standard 45 mm DIN-rail pitch. DC switching capability is specified per voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V. The screw terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, up to 2x 10 mm² max — covers most control and power wiring in a standard panel. Fuse coordination: with type 2 coordination (no welding on short circuit), use gL/gG 25 A fuses; with type 1 coordination (allow contactor replacement after fault), use gL/gG 63 A fuses. This is the spec your panel designer needs for the short-circuit protection scheme.

Frequently asked questions

Where can I buy 3RT1024-3AL20-ZX95 and get a price?

This part is sourced and quoted to order against an RFQ. Submit a request for quote (RFQ) through the storefront; availability and current pricing are confirmed at quote time.

Will 3RT1024-3AL20-ZX95 drop into a panel specified around 3RT1023-1AL20 without rewiring?

Both are S0-size SIRIUS contactors with the same 45 mm width and screw-terminal format, so the footprint and DIN-rail mounting are identical. The 3RT1024-3AL20-ZX95 carries higher motor power ratings (7.5 kW at 500 V and 690 V) and a higher AC-4 breaking current (12.5 A), so it is a functional upgrade — but verify that your control voltage and auxiliary contact configuration match, as the -ZX95 suffix may indicate a special version.
