Siemens 3RT2026-2BB40 AC Contactor 24VDC Coil

Siemens 3RT2026-2BB40 is a three-pole power contactor from the SIRIUS 3RT2 family that uses a 24 V DC coil to control AC-3e/AC-3 loads in industrial automation, offering robust switching for motor-start and other inductive applications. The main circuit is rated for 25 A and 11 kW at 400 V, providing a solid capability for three-phase motors and similar loads while maintaining a compact S0 form-factor and reliable operation. An auxiliary contact block delivers 1 normally open and 1 normally closed contact (1 NO + 1 NC) for basic control signaling, and the device features spring-loaded terminals to simplify wiring and maintain secure connections in control panels. Designed for dependable performance in harsh environments, this Siemens contactor combines a DC-coil drive with a high-rated AC-3 main circuit, making it a precise fit for panel builders seeking a compact, tested solution for motor control and inductive switching.
