Product Description

Uchihashi Tamura 5A 250V Thermal Cutoff Fuse L4F 127C Thermal Fuse

Product Description:

A thermal fuse, also known as a thermal cutoff or thermal link, is a safety device used to protect electrical appliances and circuits from overheating. It operates by interrupting the electrical current when the temperature exceeds a predetermined threshold, thereby preventing potential fire hazards or damage to the equipment.

Features:

The fuse is calibrated to respond to a specific temperature.
Ceramic case, heating response quickly.
Stable operation and high precision.
Small and lightweight, making it easy to integrate into various devices.
Free of lead (Pb) and cadmium (Cd) and is RoHS and REACH compliant.
Epoxy resin sealing.
Very simple structure, the product is less affected by time changes, and the reliability is high.

Working Principle

When ambient temperature rises to its operating temperature, the fusible alloy will melt and shrink into bulb on both sides of pin, with the help of surface tension and special resin, cut off the circuit permanently.
