Product details

It provides 2 normally open instantaneous contacts rated at 10 A at 24 V, making it suitable for extending the I/O of a main contactor or for interlocking sequences in a control panel.

The solid conductor capacity accepts 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm², covering typical control wiring sizes.

Environmental and electrical ratings

Shock resistance is rated at 10g for 5 ms and 5g for 10 ms. The coil includes a built-in varistor for surge suppression, reducing back-EMF when de-energized. Rated operational current at 24 V is 10 A, derating to 6 A at 230 V AC and 3 A at 400 V AC.

Frequently asked questions

What is the closest functional alternative — 3RT1017-1AP01?

The 3RT1017-1AP01 is a power contactor, not a direct functional substitute. The 3RH1122-1TP00-0KV0 is an auxiliary contactor designed for control-circuit switching; a 3RT series contactor serves main motor loads. They are not drop-in replacements without rewiring the control circuit.

What is the depth of this contactor?

The depth is 72 mm.

What conductor sizes does it accept?

It accepts 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm² solid conductors.

Will it fit in a panel designed for a 3RT1017-1AP01?

The 3RH1122-1TP00-0KV0 shares the size S00 frame with many 3RT contactors, so the footprint and DIN-rail mounting are compatible. However, verify the coil voltage (24 V with varistor) and contact configuration (2 NO) match the control scheme — the wiring differs from a power contactor.
