0LMF008.U

0LMF008.U Application Field and Working Principle

The 0LMF008.U type fuse is a miniature time-delay current-limiting fuse with an interrupting rating of 20 kV and 200Vac. It is designed to protect lighting fixtures, distribution systems, power supplies, motors, and control circuits.

The 0LMF008.U is a dual-element fuse, meaning that it comprises two distinct elements: a time-delay characteristic element and a current-limiting characteristic element. The time-delay element is designed to maximize the delay while the current-limiting element is designed to trip the fuse at a predetermined current. The design of the 0LMF008.U fuse allows it to be both current-limiting and time-delay, providing the best of both functions.

The 0LMF008.U fuse is designed to operate as a current-limiting device, meaning that it will trip when the current reaches a predetermined value. This value is determined by the fuse design, and is usually printed on the fuse body. The fuse will also trip if it is overloaded beyond its current-limiting capacity. This feature provides protection to the circuit being protected. The time-delay element of the fuse delays the trip time, providing protection to downstream devices from short duration transient overcurrents.

The 0LMF008.U fuse has two separate and distinct ratings. The current-limiting rating is the peak current value at which the fuse will trip, typically 1.1In or 1.16In. The time-delay rating is the maximum time that the fuse will delay tripping, typically 35ms. The ratings are generally printed on the fuse body for easy reference.

The 0LMF008.U fuse is recommended for intermittent overcurrent protection of lighting fixtures, distribution systems, power supplies, motor circuits, and control circuits. It provides both current-limiting and time-delay protection. It is available in a variety of ampere ratings to meet various application requirements. The 0LMF008.U fuse is made from solid-state materials with excellent quality and reliability.
