Lightning Protection 16A 20A 115C 300V 20KA Thermal Fuse

A thermal fuse or thermal cutoff is a safety device which open circuits against overheat. It detects the heat caused by the over-current due to short circuit or component breakdown. Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would. A thermal fuse must be replaced when it fails or is triggered.

Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature.

Specification

Advantages

1. Confidential alloy formula technology to ensure stable operation and high precision.
2. Complete product quality management system to ensure high consistency and reliability.
3.Plastic case, good insulation, easy to install.
4. Epoxy resin package, good product sealing.

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.
