Product Positioning

The 3RT2026-1AP00 is a standard frame contactor from the Siemens SIRIUS 3RT2 series S00. It is a three-pole, AC-3 rated 25A, 400V contactor capable of switching 11kW motor loads. The coil specifications are 230V AC, 50Hz single frequency, which is a common control voltage in European factories and some control panels in Taiwan. With built-in 1NO+1NC auxiliary contacts, it can simultaneously provide status feedback and interlocking signals, completing basic monitoring circuit designs without the need for additional auxiliary contact modules.

Core Product Advantages and Features

S00 miniaturized frame

With dimensions of 45×85×97mm, it is compact in size compared to other 25A-class circuits and can easily accommodate applications with high-density distribution box layouts.

230V AC 50Hz coil

It is compatible with most European control circuit voltages and features a single rated frequency design. The coil heating and holding power have been verified in-house to ensure stable operation.

1NO+1NC Built-in Auxiliary Contacts

Without the need for additional auxiliary modules, normally open feedback signals and normally closed interlock signals can be obtained simultaneously, simplifying control panel wiring.

690V insulation/IP20 protection

The main and auxiliary circuits have an insulation voltage of 690V, a rated impulse withstand voltage of 6kV, and a mechanical life of 10 million cycles, conforming to IEC 60947-4-1 standards.
