Siemens 3RT2026-2AG20 Power Contactor 110V AC 25A/11kW

Product Positioning

The Siemens SIRIUS 3RT2026-2AG20 is equipped with a 110V AC (50/60Hz) coil. The AC-3 main circuit is rated at 25A, and 400V corresponds to 11kW. 110V AC is a common voltage on the secondary side of the control transformer of many machine tools and production equipment. Existing 110V control circuit wiring can be directly used. Spring terminals are equipped with 1NO+1NC auxiliary contacts, making installation and maintenance quick.

Core Product Advantages and Features

110V AC coil has high versatility

The coil voltage is 110V AC and supports 50/60Hz dual frequency, which is compatible with the output voltage of most machine tool control transformers. When replacing existing contactors, there is no need to change the control circuit design.

25A/11kW main circuit

The AC-3 has a rated current of 25A and corresponds to a motor power of 11kW at 400V. The S0 frame shares the main contact with the 3RT2026 series, making it suitable for direct starting of general loads such as pumps and fans.

Quick installation of spring terminals

Both the main and auxiliary circuits use spring-loaded screwless terminals, and the crimping method can shorten the time required for control panel assembly, maintenance, and parts replacement.

1NO+1NC auxiliary contact

It has one normally open and one normally closed instantaneous auxiliary contact built in, which can provide feedback on the contactor's operating status and meet the needs of general monitoring and interlocking circuits.
