ABB Hi-Tech Valiant wildfire mitigation fuse
By Anthony Capkun
March 3, 2022 – ABB Installation Products’ new Hi-Tech Valiant current-limiting fuse is designed to contain sparks that could otherwise be emitted during fuse operation and fall on dry vegetation, thereby helping to prevent wildfires.
ABB’s fuse technology employs a sensor to protect against undetected fuse damage, and provides visual indication after operation. It helps address the prevention and mitigation of wildfires by interrupting the current in less than a 1/4 cycle, and preventing expulsive gases, showers and external heat from being generated during fuse operation.
The fuse incorporates a patent-pending engagement pin to ensure vertical and rotational alignment, and installs using standard field installation procedures.
