Siemens SIRIUS 3RT2038-3CL24-3MA0 Power Contactor, 80A, 37kW (S2), 230V AC Coil, Spring-Loaded/Screw Terminal, 2 NO + 2 NC Aux Original Brand New

Overview

The Siemens SIRIUS 3RT2038-3CL24-3MA0 is a high-performance, 3-pole power contactor designed for reliable switching of motors and other industrial loads up to 80 Amps (AC-3e/AC-3) or 37 kW at $400\text{ V}$. This contactor belongs to the compact and versatile SIRIUS 3RT20 series (Size S2), known for their robustness and system-wide compatibility. It is factory-equipped with a $230\text{ V AC},50/60\text{ Hz}$ control coil and features integrated surge protection via a plugged-in varistor for enhanced coil longevity and system stability.

Benefit

1. High Performance in a Compact Design (Size S2): Offers a high switching capacity of 80A / 37kW while maintaining a smaller footprint, optimizing space in your control panel.
2. Increased Reliability: Integrated, plugged-in varistor surge suppression protects the control coil against voltage peaks, ensuring long-term operational stability.
3. Fast and Secure Wiring: Features a dual-terminal design with robust screw terminals for the main circuit and vibration-proof, maintenance-free spring-loaded terminals for the control/auxiliary circuit.
4. Ready for Motor Control: With a standard 2 NO + 2 NC captive auxiliary switch, it is ideal for interlocking, signaling, and integrating into complex motor starter combinations (e.g., reversing starters, wye-delta starters).
5. Global Standard & Compatibility (SIRIUS System): As part of the Siemens SIRIUS modular system, it is globally approved (IEC, UL/CSA) and ensures seamless, coordinated integration with other SIRIUS components like overload relays and circuit breakers.
