Product details

It carries an AC-3 rated power of 11 kW at 690 V, and also 11 kW at 500 V, with a corresponding AC-4 current rating of 15.5 A at 400 V for reversing or inching duty. The 24 VAC coil operates at both 50 Hz and 60 Hz, with a tolerance range of 0.8...1.1 times rated voltage at 50 Hz and 0.85...1.1 at 60 Hz.

Solid wire acceptance: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max. 2x (0.75...4 mm²). Stranded wire acceptance: 2x (1...2.5 mm²), 2x (2.5...6 mm²), max. 2x 10 mm². AWG equivalents for main contacts: 2x (16...12), 2x (14...10), 1x 8. The contactor has 2 instantaneous contacts (no auxiliary contact block included).

Environmental and coordination

Maximum operating altitude: 2,000 m. For Type 1 coordination, the required fuse is gL/gG 100 A; for Type 2 coordination, gL/gG 35 A. Mechanical life is typical 10,000,000 operations.

Frequently asked questions

What are the key ratings for the 3RT1026-1AC24?

It is a size S0 power contactor with a 24 VAC 50/60 Hz coil, rated 11 kW at 690 V AC-3 and 11 kW at 500 V AC-3. The AC-4 current rating at 400 V is 15.5 A. It has 2 instantaneous contacts and screw-type terminals.

Where can I buy the 3RT1026-1AC24?

Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will the 3RT1026-1AC24 drop into a panel specified around the 3RT1023-1AL20?

Both are SIRIUS size S0 contactors with the same DIN rail footprint and screw terminal pattern, so they share the same panel cut-out and mounting rail. The main difference is the coil voltage and power ratings — verify the coil voltage matches your control circuit before substituting.
