3UG4583-2CW31 SIEMENS

The 3UG4583-2CW31 insulation monitoring relay by Siemens is designed to continuously monitor the insulation resistance of ungrounded (IT) AC and DC networks, ensuring operational safety and preventing unexpected downtime. It is suitable for AC systems up to 400 V with a frequency range of 15-400 Hz, and DC systems up to 600 V. The relay offers a wide measuring range, adjustable between 1-100 kOhm and 2-200 kOhm, allowing for flexible adaptation to different application requirements. Its broad supply voltage range of 24-240 V AC/DC enhances its versatility and compatibility with various power systems. The device features a compact design with a width of 45 mm, making it easy to integrate into existing control panels. It is equipped with either 1 + 1 or 2 changeover contacts, providing flexible signaling options for alarm and control circuits. The spring-loaded terminal (push-in) design ensures quick, secure, and tool-free wiring, reducing installation time and effort. This insulation monitoring relay is essential for applications where maintaining high insulation levels is critical to prevent electrical hazards and ensure continuous operation. It provides reliable and accurate monitoring, contributing to the overall safety and efficiency of electrical systems.
