Product details

Product identity and sourcing posture

Switching frequency and duty ratings

Maximum mechanical switching rate is 1 000 1/h under AC-1 resistive load, dropping to 750 1/h for AC-2 and AC-3 motor duty, and 250 1/h for AC-4 plugging or inching service.

Mounting and environmental tolerances

Wiring and auxiliary contact provisions

Main and coil terminals accept solid or stranded conductors from 1 to 10 mm², with dual-wire capability for 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) on the coil circuit. The contactor includes an auxiliary switch block, allowing local status feedback without a separate add-on module.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, height 85 mm, depth 97 mm. Minimum clearance around the contactor is 10 mm upward, forward, and downward, and 6 mm at the sides.

What wire sizes does the 3RT2028-1AP60 accept?

Main and coil terminals accept solid or stranded wire from 1 to 10 mm². The coil terminals also accept two wires per clamp: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).

Does this contactor include an auxiliary contact?

Yes, it is equipped with an auxiliary switch as standard.
