Product details

The Siemens 3RT2526-2AB00 is a SIRIUS S0 contactor with spring-type terminals — no screw torque, no loosening over vibration cycles. Coil pulls 24 V at 50 Hz. That covers control transformers, small motor loads, and resistive heater banks inside a panel. Side-by-side mounting is supported with zero spacing.

Ratings that drive the fit

The AC-1 maximum switching frequency is 1 000 operations per hour; at DC it's 1 500 per hour. Arcing time is 10 to 10 ms — consistent, predictable break. Mechanical endurance is 10 000 000 cycles typical. That -25 °C floor is important: if your panel sits in an unheated space in a cold climate, this contactor starts and holds without a heater.

Spring-type terminals accept solid or stranded conductors 2x (0.5... 2.5 mm²). No screwdriver torque check — push in, release, done. This saves a DIN-rail slot and one wiring step.

Frequently asked questions

What are the key switching ratings for 3RT2526-2AB00?

At 24 V rated value it switches 10 A; at 400 V rated value it switches 3 A; at 230 V rated value it switches 10 A. The coil is 24 V at 50 Hz.

Will 3RT2526-2AB00 drop into a panel specified around 3RT2526-1AB00?

Both are SIRIUS S0 contactors on the same 35 mm DIN-rail footprint. The key difference is termination: the -2AB00 uses spring-type terminals; the -1AB00 uses screw terminals. Panel cutout and mounting position rules are identical. No rewiring of the rail or enclosure needed — just the conductor termination style changes.
