Reliable Protection for Low-Current Circuits
Fast-acting fuses are designed to interrupt excessive current quickly, making them suitable for circuits containing components that may be damaged by relatively brief overcurrent conditions. When the current exceeds the fuse’s operating threshold, the fuse element opens the circuit and helps prevent further electrical or thermal damage.
The Mersen D077812 is intended for use in a correctly rated and compatible fuse holder. When selecting a replacement fuse, the current rating, voltage rating, physical dimensions and operating characteristic should all match the requirements of the protected equipment.
