1. Structure:

The most commonly used circuit overcurrent protection components are small canned fuses, which are composed of two main parts: a tube body with metal connection terminals at both ends and a metal melt in the tube. The function is to support and connect, most of the One Switch Three Pin Round Socket with Lamp Mould's appearance is cylindrical, which is called tubular; the key function is determined by the internal melt.

2. Function:

One Switch Three Pin Round Socket with Lamp Mould is connected in series in the circuit, and generally requires its resistance to be small (low power consumption), so when the circuit is working normally, the fuse is only equivalent to a wire, which can be used stably for a long time. ;When the current fluctuates due to power supply or external interference, the fuse can also withstand a certain range of overload; only when there is a large overload current in the circuit-fault or short-circuit-, the fuse will operate, by breaking the current. Protect the safety of the circuit.

3. principle:

When the One Switch Three Pin Round Socket with Lamp Mould is energized, the heat converted by the current will increase the temperature of the melt. When the normal operating current or the allowable overload current is loaded, the heat generated by the current will pass through the melt, the shell and the surrounding area. The heat radiated by the environment, convection and conduction can gradually reach a balance; if the heat dissipation rate cannot keep up with the heat generation, the heat will accumulate on the melt one by one, causing the melt temperature to rise. The melting point of the molten material will melt it, thereby breaking the current and playing a role in safety protection.
