Siemens SIRIUS 3RT2015-1BM41 Power Contactor, 3-Pole, 7A, 3kW/400V, 220V DC Coil, Size S00, Screw Terminal Original Brand New

Overview

The Siemens SIRIUS 3RT2015-1BM41 is a high-performance, compact 3-pole power contactor designed for reliable switching of motors and other industrial loads up to 7 A (AC-3e/AC-3) or 3 kW at 400 V. Part of the globally successful SIRIUS modular system, this size S00 contactor offers exceptional contact reliability and a long mechanical service life (up to 30 million operating cycles). It features a 220 V DC control voltage and a built-in 1 NO (Normally Open) auxiliary contact, making it a versatile component for modern control panels and motor feeder applications. The robust screw terminals ensure secure and straightforward wiring.

Function/Application

The Siemens 3RT2015-1BM41 power contactor is primarily used for switching 3-phase AC motors and other resistive or inductive loads. Its 3-pole design handles the main circuit, while the integrated 1 NO auxiliary contact provides basic feedback or interlocking functionality within the control circuit. It is a critical component in:

• Direct-on-line (DOL) motor starters
• Reversing contactor assemblies
• General load switching (e.g., heating, lighting)
• Automation and machine control systems
