Introduction

Fuses are commonly used in electrical and electronic circuits to provide protection by limiting the current to a safe level in the event of a short circuit or overload. The MDA-15-100UNP-R is a class J, high interrupting capacity fuse manufactured by Eaton. It is part of the company\'s MDL series of fuses which are designed for multiple types of system applications, from motor branch circuits, to lighting systems, to industrial control.

Applications

The MDA-15-100UNP-R is a 15 amp, 100 volt AC/DC rated, UL listed Class J fuse. It is available in two configurations, one with an ampere rating of 15 amps and the other with an ampere rating of 100 amps. It is designed to provide protection for single and three-phase motor branch circuits, lighting systems, large motor clusters, and industrial control systems. It also provides additional protection in conditions where power surges and voltage transients are common.

Features

The MDA-15-100UNP-R features a UL 94V-0 thermoplastic body, silver-plate terminals, and a Resin-impregnated fiberglass construction for reliable circuit protection, vibration resistance and improved safety. This fuse also has an interrupting rating of 200K Amps at 150V AC, making it highly effective for the prevention of circuit overloads and short circuits. Additionally, it has an operating temperature range of -55°C to 125°C and is approved for use in the United States, Canada, and Mexico.

Working Principle

The MDA-15-100UNP-R operates on the principle of thermal expansion and conduction of heat. When the current through the fuse exceeds the rated current of the fuse, the element within the fuse expands, creating a break in the circuit and cutting off the flow of electricity. This type of fuse is designed to be resettable, meaning that once the over-current condition has been cleared, the element cools and the circuit is able to be re-energized.

Conclusion

The MDA-15-100UNP-R is a reliable and highly effective class J fuse for multiple types of system applications. Its durable thermoplastic body and Resin-impregnated fiberglass construction provide superior vibration resistance and improved safety. Its wide operating temperature range and high interrupting rating make it an ideal choice for protecting motor branch circuits, lighting systems, motor clusters, and industrial control systems from overloads and short circuits in conditions where power surges and voltage transients are common.
