Siemens 3RT1054-6AB36 power contactor, AC-3e/AC-3 115 A, 55 kW / 400 V, AC (50-60 Hz) / DC Uc: 23-26 V 3-pole, auxiliary contacts 2 NO + 2 NC drive: conventional main circuit: busbar control and auxiliary circuit: screw terminal
Overview
The Siemens SIRIUS 3RT1054-6AB36 Power Contactor is a high-performance, 3-pole switching device from the proven SIRIUS modular system, specifically designed for reliably switching AC-3e/AC-3 motor loads up to 115 A (55 kW at 400 V). As a Size S6 IEC power contactor, it offers a robust solution for demanding industrial applications.
This model is equipped with a versatile 23-26V AC/DC (Universal Current – UC) conventional drive coil, ensuring reliable operation across different control voltages. Its main circuit uses busbar terminals for high-current connections, while the control and auxiliary circuits feature convenient screw terminals. It comes with pre-installed auxiliary contacts (2 NO + 2 NC), simplifying wiring and monitoring.
