Siemens 3RT2517-2BM40 Power Contactor 4-Pole, AC-3, 12A, 5.5kW / 400V, 220V DC, Spring-Loaded Terminal Original Brand New

Overview

The Siemens SIRIUS 3RT2517-2BM40 is a high-performance, compact 4-pole power contactor from the trusted SIRIUS 3RT2 series, specifically designed for specialized applications such as reversing motor control (e.g., hoisting gear) or switching two independent loads.

This robust device features a main contact configuration of 2 Normally Open (NO) + 2 Normally Closed (NC) poles, making it ideal for polarity-changing circuits. It is rated for an operational current of 12 A (AC-3) / 22 A (AC-1) and handles up to 5.5 kW at 400 V. The control circuit operates on a 220 V DC coil, and the main and auxiliary circuits utilize convenient, reliable spring-type terminals for fast, vibration-proof, and maintenance-free wiring. Its compact Size S00 construction ensures optimal panel space utilization.
