Overview

The Mersen GTL15 (SKU: GTL15) is a non-time-delay plug fuse designed for reliable overcurrent protection in industrial and residential applications. Rated for 125 Volts and 15 Amps, this fuse is part of Mersen's GP series, specifically the GTL sub-series indicating its non-time-delay characteristic. It is engineered for use in receptacle and lighting circuits, where rapid interruption of fault currents is essential. The fuse features a low melting-point temperature element, ensuring swift response to overloads and short circuits, thereby safeguarding connected equipment and preventing potential damage. This fuse is suitable for a broad range of common electrical circuits, making it a versatile choice for electricians and facility managers. While not explicitly designated as Type P or Type D for Canadian requirements, its fundamental design principles align with the need for dependable protection. For applications requiring specific Canadian electrical code compliance, Mersen offers Type P fuses for non-motor loads and Type D fuses for electrical heating and cyclical load circuits, both featuring low melting-point elements. The GTL15's 125V rating and 15A current rating make it a standard selection for many household appliances, lighting fixtures, general-purpose outlets, and supplemental protection in industrial control panels and auxiliary circuits. Mersen is a globally recognized leader in electrical protection, and the GTL15 embodies their commitment to quality and performance. Its robust construction and precise calibration offer dependable protection, minimizing downtime and ensuring operational continuity. When selecting fuses, it is crucial to match the fuse type to the circuit's requirements; non-time-delay fuses like the GTL15 are preferred for circuits where immediate fault interruption is critical, as opposed to motor loads which may require time-delay fuses to handle inrush currents. The UNSPSC code 39121605 categorizes this product under 'Fuses', highlighting its fundamental role in electrical safety infrastructure. Trust Mersen for dependable protection that keeps your systems running safely and efficiently.

The National Electric Code now permits Edison-base fuses to be used only for replacements in existing installations, and then, only when there is no evidence of overfusing or tampering. All new Edison-based fuseholders must have Type S fuse adapters installed before they are placed in service. Designed to prevent installation of wrong size fuses, Type S Adapters (SAO series) screw into Edison-base fuseholders so they may accept Type S fuses. Once installed the adapters cannot be removed. To prevent shunting of open fuses or overfusing, and to reduce nuisance fuse opening, it is recommended that SAO adapters with properly rated SLO or SOO series fuses be installed in all Edison-base fuseholders.
