Product Positioning

The Siemens SIRIUS 3RT2026-2AC20 is equipped with a 24V AC (50/60Hz) coil. The AC-3 main circuit is rated at 25A, and 400V corresponds to 11kW. The 24V AC is a low-voltage control circuit, which is safer for maintenance personnel. It is often used in machine control panels that need to comply with low-voltage safety regulations. The spring terminals are equipped with 1NO+1NC auxiliary contacts, which makes wiring and subsequent maintenance convenient.

Core Product Advantages and Features

24V AC low-voltage safety coil

With a coil voltage of 24V AC and support for 50/60Hz dual frequency, it belongs to the low-voltage control circuit, which can reduce the operational risks for maintenance personnel when accessing the control circuit. It is commonly found in production line control panels with strict safety regulations.

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 same main contact design as the 3RT2026 series, which is more than enough for direct starting of general motors.

Screwless spring terminals

Both the main and auxiliary circuits use spring-type terminals, which can be powered on immediately after crimping, thus shortening the assembly time of the control panel and the time required for future maintenance and replacement.

1NO+1NC auxiliary contact

It has one normally open and one normally closed instantaneous auxiliary contact built in, which can be used as a feedback signal for operating status or an interlock signal to meet the general motor control and monitoring needs.
