Product details

Switching duty and auxiliary contacts

Rated for 1,000 switching cycles per hour at AC-1, AC-2, AC-3, and AC-3e; drops to 300 cycles/hr at AC-4 for heavy motor inching or plugging. The built-in auxiliary switch (1 NO + 1 NC) handles 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, and 11 A at 480 V — covers most control-circuit voltages on the plant floor.

Wiring and environmental limits

Spring-type terminals accept 1…10 mm² solid or stranded main conductors, and 2x (0.5…2.5 mm²) for auxiliary wiring — no screwdriver torque needed, just strip and push. Operating temperature range -25…+60 °C; storage from -55…+80 °C.

Frequently asked questions

How do I get current pricing and availability for 3RT2024-2AB00-1AA0?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time through independent distribution channels.

What is the depth of 3RT2024-2AB00-1AA0?

The depth is 97 mm. Overall dimensions are 45 mm wide by 102 mm high.

What wire sizes does the spring terminal accept?

Main terminals accept 1…10 mm² solid or stranded. Auxiliary terminals accept 2x (0.5…2.5 mm²) solid or stranded.

Will 3RT2024-2AB00-1AA0 drop into a panel specified for 3RT2024-1AL20-ZX95 without rewiring?

Both are size S0 contactors with the same mounting footprint on 35 mm DIN rail, so the mechanical fit is identical. Terminal type differs — this unit uses spring-type terminals; verify the peer's terminal type before assuming no wiring change.
