Fusesaver™

The world's fastest vacuum circuit-breaker. Watch how quick and easy it can be installed.
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.

Minimising the risk of bushfires with Fusesaver™

On extreme risk bushfire days, it is critical to eliminate any probability of faults on the electrical network igniting a fire. Find out how the Fusesaver™ can support you minimising the risk of bushfires.
