Rezap Faultmaster

LV multi-shot auto-recloser

Protects the LV network during intermittent LV cable faults and safely restores customer supplies fast while assisting fault location.

Overview

Intermittent faults can be a major challenge for customers, often requiring an hour or more for operators to restore supply.

Rezap Faultmaster is a multi-shot circuit breaker and auto-recloser that rapidly reconnects customers after intermittent LV cable faults, minimising interruptions while keeping staff safe.

The smart device interrupts supply in the event of an over-current event, automatically re-energising the circuit after a short delay. Intelligent electronics and programmable delay characteristics allow intermittent faults to be cleared and restore supplies, or conditioned to accelerate collection of fault data to allow subsequent repair.

Rezap Faultmaster also collects power quality and fault information to enable single-ended fault location.
