Siemens SIRIUS 3RT1054-2AF36 Power Contactor, 115A, 55kW, AC-3, 110-127V AC/DC Coil, Spring-Loaded Terminals Original Brand New

Overview

The Siemens SIRIUS 3RT1054-2AF36 Power Contactor is a robust and reliable switching device from the proven SIRIUS modular system, specifically designed for controlling electric motors and other industrial loads up to 115 Amperes (AC-3e/AC-3) and 55 kW at 400 V. This high-performance 3-pole contactor is engineered for demanding industrial environments and is an ideal component for any load feeder or motor starting application.

This specific model (Size S6) features a versatile 110-127 V AC (50/60 Hz) / DC conventional coil drive, ensuring global compatibility and reliable operation across both AC and DC control voltages. The main circuit employs busbar connection for efficient power distribution, while the control and auxiliary circuits utilize spring-loaded terminals for fast, vibration-proof, and maintenance-free wiring.
