Product Positioning

The Siemens SIRIUS 3RT2026-2BB40 is a standard S0-frame power contactor. It features an AC-3 main circuit rated at 25A and can control an 11kW motor at 400V. The 24V DC coil is a basic model without built-in suppression components, but external surge protection can be added according to site requirements. Its spring-loaded terminals allow for quick wiring, making it the most economical and versatile choice for 24V DC control circuits.

Core Product Advantages and Features
Basic 24V DC coil
The coil is a standard 24V DC type, without built-in rheostat or diode, and has high wiring flexibility, making it suitable for projects with existing surge protection specifications or those that want to select their own suppression components.
25A/11kW main circuit strength
The AC-3 has a rated current of 25A and 400V, corresponding to an 11kW motor power. The S0 frame shares the main contact with the 3RT2026 series, and can directly start general loads such as pumps, fans, and mixers.
Screwless spring terminals
Both the main and auxiliary circuits use spring-type terminals, which are not easily loosened due to vibration after crimping, thus shortening the wiring time for control panel production and after-sales maintenance.
1NO+1NC Assist Feedback
It has one normally open and one normally closed instantaneous auxiliary contact built in, which can directly provide the contactor's operating status to the PLC monitoring or indication circuit.
