        Introduction

        The smart device to improve reliability and safety

        By virtually eliminating the impacts of temporary faults on lateral lines, Fusesaver helps utilities to increase network reliability while minimising operating costs of overhead MV networks. The exceptional small footprint and light weight of the device enables a quick and easy installation and fast commissioning. Self-powered from line current, the circuit breaker has the capability for multi-phase fault clearance for both transient and permanent faults. The smart system provides wireless connectivity for remote access and can be easily integrated into utilities SCADA network via a Remote Control Unit (RCU).

        Higher availability for your distribution network

        Fusesaver can detect, open and clear a fault in as little as one-half cycle (10ms) and is configurable to either protect or replace the fuse.

        Fusesaver can be installed in series with the fuse

        When it senses a fault current, it will open before the fuse can melt, and clear a transient fault. 

        Then the Fusesaver closes again reconnecting supply. If the line is still faulted the fuse will now operate to clear the permanent fault. This is the traditional Open-Close (OC) Fusesaver.

         

        Replace the fuse altogether

        When installed in this manner, the Fusesaver can perform the same Open-Close functionality to clear a transient fault but can also perform a second "Open" operation (OCO) to clear a permanent fault.
