Product details

Rated for 7.5 kW at 690 V and 7.5 kW at 500 V, this contactor handles motor loads up to those power levels in AC-3 duty.

The S0 frame occupies 45 mm of DIN rail width, leaving room for auxiliary contact blocks or overload relays in the same row. Wire termination: solid conductors accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). Stranded conductors accept 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), or max 2x 10 mm². AWG equivalents for main contacts: 2x (16 to 12), 2x (14 to 10), or 1x 8. These ranges cover most panel wiring from control-circuit sizes up to motor feeders.

For Type 2 coordination (no welding, contactor remains operational after a fault), the required fuse is gL/gG 25 A. These values guide the selection of branch-circuit protection for the motor starter assembly. The operating factor at 60 Hz is 0.8 to 1.1, which defines the permissible duty cycle relative to the rated current.

Frequently asked questions

What is the depth of 3RT1024-1AT60?

The depth is 91 mm. This is the dimension from the mounting surface to the furthest projection, which matters when fitting into shallow enclosures or when planning clearance behind the DIN rail.

What wire sizes does the 3RT1024-1AT60 accept?

Solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded: 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG main contacts: 2x (16 to 12), 2x (14 to 10), 1x 8.

Where can I buy 3RT1024-1AT60?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 3RT1024-1AT60 drop into a panel specified around 3RT1023-1AL20?

Both are SIRIUS S0 frame contactors with the same 45 mm width and DIN rail mounting, so the physical footprint and rail position are identical. The difference is in the coil voltage and power ratings — verify the coil voltage matches your control circuit and that the 3RT1024-1AT60's 7.5 kW at 690 V meets or exceeds the original specification before substituting.
