OT630E03P

This relay serves as a fundamental backup or primary protection device in medium-voltage (MV) and high-voltage (HV) networks. Its core principle is to measure the current via connected Current Transformers (CTs) and, if the current exceeds a preset threshold for a duration defined by an inverse time curve, it mechanically closes its output contacts to trip a circuit breaker. Its self-powered nature makes it exceptionally reliable and ideal for critical protection where control power failure must not compromise safety.
