Overview
The Siemens SIRIUS 3RT2536-1AB00 Power Contactor is a high-performance, robust switching device designed for controlling electric motors and other resistive loads in demanding industrial applications. This specific model is a 4-pole contactor from the compact SIRIUS 3RT2 series, engineered for maximum efficiency in the control panel. It is rated for AC-3 switching duty up to 41 A and 22 kW at 400 V. Featuring a reliable 24 V AC, 50 Hz control coil, the contactor utilizes screw terminals for secure and straightforward wiring. Its compact Size S2 design allows for space-saving installation.
Key Function
-
Motor Control: Safely and efficiently switches the power supply to 3-phase AC motors (AC-3 duty).
-
Load Switching: Suitable for switching other heavy-duty AC loads within its current and power ratings.
-
Isolation: Provides a clear, reliable electrical separation when the coil is de-energized.
-
Circuit Feedback: Built-in 1 NO + 1 NC auxiliary contacts provide status feedback to the control system (e.g., PLC).
-
4-Pole Switching: Offers simultaneous control over four separate main power circuits, often used for specific three-phase applications requiring a switched neutral, or for two separate single-phase circuits.
