AC-3e/AC-3 duty 7A current rating 24V DC coil Integrated suppression diode 1 NC auxiliary contact Spring-loaded terminals Size S00

The Siemens 3RT2015-2FB42 is a 3-pole power contactor designed for AC-3e/AC-3 applications, rated for 7A and 3kW at 400V. This model features a 24V DC coil and includes an integrated suppression diode for protection against voltage spikes from inductive loads. It is equipped with one normally closed (NC) auxiliary contact and uses spring-loaded terminals for secure and vibration-resistant connections within its size S00 frame.

This contactor is suitable for motor control and switching applications in industrial automation, manufacturing, and control systems where DC control voltage is employed and protection against inductive transients is necessary, alongside the need for a normally closed auxiliary contact.
