Overview

The Mersen GSL15 is a Type S plug fuse designed for reliable overcurrent protection in both industrial and residential applications. Rated for 125 Volts and 15 Amps, this fuse is part of Mersen's GSL series, offering essential safety for receptacle and lighting circuits. As a non-time-delay fuse, it provides rapid response to overloads and short circuits, safeguarding equipment. The Type S designation ensures tamper resistance, a critical safety feature that prevents the use of incorrect fuse ratings and enhances overall electrical system safety. This fuse is suitable for general-purpose circuits where quick interruption is required. With a 10kA interrupting rating, the GSL15 effectively handles fault conditions. It is manufactured in the USA and adheres to stringent quality standards. For Canadian requirements, Mersen offers specific Type P fuses for non-motor loads and Type D fuses for electrical heating and cyclical load circuits, both of which have low melting-point temperature elements. The GSL15, however, is designed for standard North American installations. Its compact design allows for easy integration into standard fuse holders and panels, minimizing downtime during replacement. Choose the Mersen GSL15 for dependable, code-compliant overcurrent protection. Mersen plug fuses are intended for industrial and residential applications. Non time-delay fuses are available for receptacle and lighting circuits and time-delay fuses for motor loads. Type S plug fuses are time-delay and tamper resistant.
