299-1-1-51-2-9-100

Circuit breakers are essential components in electrical systems used to protect electrical systems and circuits from damage due to overloading or short circuits. They operate by automatically opening the circuit when the current in the circuit exceeds a particular set value. The 299-1-1-51-2-9-100 circuit breaker is one type of circuit breaker commonly used in many applications.

Application Field: The 299-1-1-51-2-9-100 circuit breaker is a single-pole circuit breaker commonly used to protect lighting fixtures and electrical outlets in residential aplications. It is also used in industrial and commercial settings to protect motors, generators, and other electrical equipment from damage due to overloading or short circuits. In addition, the 299-1-1-51-2-9-100 is suitable for use in power distribution panels in large facilities.

Working Principle: A 299-1-1-51-2-9-100 circuit breaker consists of a thermal-magnetic tripping system. This system is composed of two elements: a heat-sensitive element (thermal element) and a current-sensitive element (magnetic element). The thermal element is a bimetallic strip that bends when heated due to the resistance of the electric current, creating an open circuit. The magnetic element has a solenoid coil wound around an iron core. When the electric current reaches a certain threshold, the magnetic element becomes magnetised, creating a force strong enough to trip the circuit breaker.

When the current exceeds a certain level, the current flows through the thermal element and the bimetallic strip bends, opening the circuit breaker. At the same time, the current flowing through the magnetic element induces a magnetic field in the iron core, which creates a force that trips the circuit breaker. This system works to protect the electrical system and circuits from damage due to overloading or short circuits.

The 299-1-1-51-2-9-100 circuit breaker is a reliable and effective way to protect wiring against overloads and short circuits. By automatically opening the circuit in the event of an overcurrent or short circuit, the circuit breaker protects expensive electrical equipment and wiring from damage. As such, the 299-1-1-51-2-9-100 circuit breaker is an essential component in any electrical system.
