Siemens SIRIUS 3RT2346-1AN60 Contactor, 4-Pole, AC-1, 140A, 200V AC Coil, S3 Size Original Brand New

Overview

The Siemens SIRIUS 3RT2346-1AN60 Contactor is a high-performance, 4-pole device designed for reliable switching of AC-1 category loads, specifically for applications involving weak or non-inductive loads. With a robust current rating of 140 A at 400 V / 40 °C, this contactor is an essential component for various industrial control and power distribution systems.

Engineered for versatility, the 3RT2346-1AN60 features a 200 V AC coil (50 Hz) and 200-220 V (60 Hz) control voltage, ensuring compatibility with common power supplies. It comes equipped with 1 NO (normally open) + 1 NC (normally closed) auxiliary contacts, providing flexible options for control circuitry and status indication. The convenient screw terminals simplify wiring and ensure secure connections.

Part of the renowned SIRIUS 3RT2 series, this contactor is built to meet stringent international standards, including IEC 60947-1, IEC 60947-4-1, and IEC 60947-5-1 (for auxiliary switches), guaranteeing safety and performance. Its compact S3 size makes it suitable for integration into various control panels and enclosures.
