FRS-R-50ID is an electrical specialty fuse that is designed to provide thermal and overload protection for electrical circuits and protect circuit components from short-circuits. It is typically found in residential and commercial applications. This fuse is a time-delay fuse that provides delay time before opening during an overload condition, allowing the circuit to momentarily carry an overcurrent before opening the circuit.

The FRS-R-50ID is a single-piece, high-temperature, high-speed circuit protection device. It has a thermal element cutout located at the center of the fuse and the core is surrounded by an outer insulating sleeve. The thermal element cutout is designed to sense and control the rate of current cycling by utilizing a temperature sensitive material with a self-generated insulation barrier.

The thermal element cutout is constructed from a high-temperature, low-gas permeability ceramic material. This material is designed to withstand high temperature and current cycling, while also serving as an electrical insulator against electric arcs. The core of the fuse is constructed from a copper alloy material, while the outer sleeve is constructed from a glass reinforced polyester material.

The working principle of the FRS-R-50ID is based on the temperature sensing element located at the center of the fuse. As current flows through the fuse, heat is generated. As the temperature of the internal element rises, the fuse core gradually melts away, which trips the fuse and interrupts the circuit. The temperature of the fuse is maintained by the thermal element that is programmed to open the circuit when the temperature reaches a predetermined level determined by the manufacturer. This temperature level is called the fusing temperature.

The FRS-R-50ID is a reliable and effective component that can be used in a variety of applications. It is suitable for both residential and commercial applications. It is specifically designed to provide thermal and overload protection for electrical circuits and protect circuit components from short-circuits. This fuse is an economical solution that can be used to safeguard electrical systems from high current draw and components from overload conditions.
