Product details

The 24 VDC coil holds at nominal and drops out below the undervoltage threshold typical for PLC-driven outputs. Rated for AC-2 duty at 5.5 kW and AC-4 at 12.5 A, both at 400 V, this contactor handles squirrel-cage motor starting and plugging/reversing loads. The screw-type main terminals accept up to 2x 10 mm² stranded or 1x 8 AWG, making it straightforward to land in a mixed-gauge panel.

Switching Ratings and Coordination

The DC switching matrix covers 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — useful for interposing relays or small DC motor brakes. AC-12 resistive switching is rated to 10 A maximum. For motor protection, Type 2 coordination requires a 25 A gL/gG fuse; Type 1 allows up to 63 A. The 400 V AC-2 power rating (5.5 kW) matches a typical 7.5 hp motor at 400 V three-phase.

Side-by-side mounting is permitted with zero spacing, saving DIN rail space; 6 mm clearance is required at the sides for airflow if derating is a concern.

Frequently asked questions

What are the key switching ratings for this contactor?

At 400 V AC-2 duty it is rated for 5.5 kW motor load; AC-4 duty (reversing/plugging) is 12.5 A. DC switching covers 10 A at 24 V down to 0.3 A at 220 V. The coil is 24 VDC.

Will the 3RT1024-1AR60 fit a panel designed for the 3RT1023-1AL20?

Both are S0-frame contactors with the same 45 mm width and 85 mm height, so the footprint matches. The key difference is the coil voltage — the 3RT1024-1AR60 uses 24 VDC, while the 3RT1023-1AL20 uses a different coil voltage. Verify the control circuit voltage before substituting.
