Siemens 3RT2015-2BW42 SIRIUS Power Contactor, 7A, 3kW, 48V DC Coil, 1NC Aux, Spring-Loaded Terminal, Size S00 Original Brand New

Overview

The Siemens 3RT2015-2BW42 Power Contactor is a high-performance switching device from the SIRIUS 3RT2 family, designed for controlling electric motors and general-purpose loads. It features a compact Size S00 frame, making it ideal for space-saving installations in control cabinets and industrial automation panels.

This reliable 3-pole contactor is rated for 7 A (AC-3e/AC-3) operational current and a maximum switching power of 3 kW at 400 V. It is equipped with a highly efficient 48 V DC operating coil, which offers lower power consumption and superior switching reliability compared to AC coils. The inclusion of spring-loaded terminals (also known as spring-type or spring-cage terminals) ensures a quick, vibration-proof, and maintenance-free connection.
