The smart device to improve reliability and safetyBy 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.
Customer Experience Powercor Australia
How Powercor Australia minimises bushfire risks
Powercor delivers electricity to nearly 780,000 homes and businesses in Victoria (Australia). The energy distributor is a located in one of the world’s most bushfire prone areas and manages approx. 90,000 km of distribution lines (87% overhead lines). Watch how Powercor deploys Fusesaver™ on SWER lines to mitigate bushfire risk.
