    The peak of circuit protection and performance.

    As a non-renewable, current limiting fuse, The Class L fuse will trip much quicker than non-current limiting fuses, after about half a cycle. Class L fuses can be used for applications with current ratings between 60 and 6000A, and carry a voltage rating of 600V. Common applications for Class L fuses include protecting AC and DC circuits, lighting loads, circuit breakers with low interruption ratings, feeders, and service entrance equipment.

    Take your pick from time delay or fast acting fuses.

    Both time delay and fast acting versions of Class L fuses are available. In Bussmann terms, time delay Class L fuses are classified as LCL, and fast acting Class L fuses are known as LCU. Time delay fuses are a more popular option for motor and transformer loads. These electrical fuse types can handle potential surges commonly associated with motor loads without sacrificing protection or causing damage. Fast acting fuses are more common for inrush currents and applications that require a very high level of current limitation.
