ABB CM-IWN

The CM-IWN ABB Insulation Monitoring Relay is an advanced monitoring device designed to ensure the safety and reliability of electrical installations. This relay features a 1CO (1 changeover) contact configuration that can handle voltage inputs ranging from 24V to 240V AC/DC. Its compact size of 100 x 45 x 78 mm allows for easy installation on a DIN rail.

The primary function of the CM-IWN ABB is to continuously monitor the insulation resistance of electrical circuits. It provides early detection of insulation faults, such as leakages or deteriorations, which can lead to dangerous situations or equipment failures. By detecting these faults in their early stages, the relay helps prevent costly damage, downtime, and potential hazards.

Equipped with state-of-the-art technology, this insulation monitoring relay offers accurate and reliable monitoring performance. It is capable of measuring insulation resistance down to 10kΩ, ensuring precise detection of insulation faults. The relay also features adjustable threshold settings, allowing users to customize the monitoring parameters to suit their specific requirements.

The CM-IWN ABB is designed to provide clear and informative status indication. It features LED indicators for various functions, such as power supply, fault detection, and relay status.
