Product Overview
Versatile Protection and Control
This accessory module provides essential remote tripping capabilities and undervoltage protection for compatible circuit breakers. It functions as either a Shunt Trip (SHT) for remote control or an Under Voltage Release (UVR/UVRN) to safeguard equipment against voltage drops. Designed for reliable operation in power distribution systems, it ensures strict adherence to safety standards.
