Overload Protector

Overload protectors are devices used to protect electrical and electronic equipment from excessive current or power. They are part of the supply class Fuses, Arrestors, Absorbers, and Protectors in the supply group Electrical and Electronic Equipment Components.

Overload protectors are designed to detect when the current flowing through a circuit exceeds a certain threshold. When this happens, the overload protector will interrupt the circuit, preventing damage to the equipment and ensuring the safety of the users.

There are different types of overload protectors available, including fuses, circuit breakers, and thermal protectors. Fuses are typically made of a metal wire or strip that melts when the current exceeds a certain level, breaking the circuit. Circuit breakers, on the other hand, use an electromechanical mechanism to trip and open the circuit when an overload is detected. Thermal protectors rely on a bimetallic strip that bends when heated, causing the circuit to open.

Arrestors and absorbers are also part of the supply class and are used to protect against voltage surges or transients. They divert excessive voltage away from the equipment, preventing damage. Arrestors are typically used in power distribution systems, while absorbers are commonly found in electronic devices.

Overall, overload protectors are essential components in electrical and electronic systems, providing protection against excessive current, power, and voltage surges. They help ensure the safe and reliable operation of equipment and prevent damage or malfunction.
