Product details

The contactor measures 45 mm wide, 85 mm high, and 140 mm deep — a standard S0 footprint that fits existing panel layouts without re-drilling.

The 3 NO main contacts handle the load-switching path. At AC-2 duty under 400 V the contactor is rated for 4 kW, and at AC-4 under 400 V it carries 8.5 A — these are the duty-cycle ratings that govern motor switching, not the thermal continuous current. For resistive loads (AC-12) the maximum operating current is 10 A. The mechanical life of 10 million cycles means the contactor is rated for high-frequency switching applications such as conveyor or pump cycling. The coil pulls 24 V at 50 Hz with a tolerance factor of 0.8 to 1.1 — so the coil holds in reliably between 19.2 V and 26.4 V. Side-by-side mounting is permitted with 6 mm spacing to adjacent devices.

Frequently asked questions

What is the depth of 3RT1023-1AB04-ZX95?

The depth is 140 mm, which is standard for the S0 frame size.

What are the main contact ratings?

The contactor has three NO main contacts. At AC-2 under 400 V it is rated for 4 kW; at AC-4 under 400 V it carries 8.5 A. For resistive loads (AC-12) the maximum operating current is 10 A.

Where can I buy 3RT1023-1AB04-ZX95?
