Product details

SIRIUS S0 power contactor — 3RT1023-1AP04-ZX95

Rated operational current at AC-2 duty at 400 V is 4 kW; at AC-4 at 400 V it handles 8.5 A.

Front face carries IP20 protection — safe for finger contact in an enclosed panel; the terminal area is rated IP00, so live parts are exposed during wiring. Wire capacity on the main circuit: solid conductors accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). Stranded conductors: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents: 2x (16 to 12), 2x (14 to 10), 1x 8. For type 1 coordination, use a 63 A gL/gG fuse; for type 2, a 25 A gL/gG fuse is required.

Frequently asked questions

How do I get current pricing and availability for 3RT1023-1AP04-ZX95?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time — we source this part to order through independent distribution.

What is 3RT1023-1AP04-ZX95's listed depth?

The depth is 140 mm. Combined with the 45 mm width and 85 mm height, it occupies a standard S0 footprint on the DIN rail.

What compliance documentation does this brand provide for 3RT1023-1AP04-ZX95?

The SIRIUS series carries CE marking under the Low Voltage Directive and is UL/CSA recognized. RoHS and REACH declarations are available from the manufacturer on request.

Will 3RT1023-1AP04-ZX95 drop into a panel specified around 3RT1023-1AL20 without rewiring?

Both are SIRIUS S0 contactors with the same 45 mm width and DIN-rail mounting, so the mechanical fit is identical. However, the coil voltage differs — this unit is 230 V 50 Hz, while the 1AL20 variant uses a different coil. Verify the control voltage matches your circuit before substitution.
