Willmall fuses protect circuits by clearing fault current before it damages equipment, giving predictable protection across many applications.
It interrupts a circuit when fault current exceeds its rating, protecting the circuit and equipment from excessive current.
A fuse clears once and is replaced, while a breaker can be reset after tripping and is often used where frequent operation is expected.
The rating is chosen for the continuous load current, the fault level of the circuit, and coordination with upstream protection.
They are used in distribution boards, equipment protection, motor circuits, and DC and PV systems.
It defines how quickly the fuse clears at different currents, matching protection to loads that tolerate brief surges.
