Circuit Breakers

Circuit Breakers are essential components in the power system world. They are designed to protect and interrupt the electric circuit when a fault occurs in the system. In essence, they protect electrical equipment from damage due to overcurrent and short circuits. The 299-3-21682-1 circuit breaker is one such device.

Application Field and Working Principle

The 299-3-21682-1 circuit breaker is used in residential, commercial and industrial buildings for protection against overcurrent and short circuits. It is also used in utility substations and basic industries. The device consists of a frame, a base, and a trip unit. The frame contains the circuit breaker terminals, which are connected to a set of terminals on the base. The trip unit contains a main switch, a thermal magnetic cutting element, and an over-current monitor.

The main switch is responsible for breaking the connection between the supply line and the load when an overload or short circuit occurs. When the trip unit senses an over-current, the thermal magnetic element is automatically activated and the main switch is opened. The over-current monitor is also used to protect against unsustainable levels of current. It can set an upper limit to the amount of electric current that can flow before the current is shut off automatically.

The 299-3-21682-1 circuit breaker has the advantage of providing quick and reliable protection against both overloads and short circuits. It is designed to detect and interrupt a circuit if the current level rises above the pre-set limit. It is also able to reset quickly and automatically once the current level normalizes. Additionally, this type of breaker can be adjusted easily to suit customer requirements.

The 299-3-21682-1 circuit breaker is an ideal device for various kinds of applications. It is highly reliable, durable, cost-effective, and easy to install. It is also energy-efficient and offers outstanding over-current protection. With its advanced features and capabilities, it is widely used in residential, commercial, and industrial buildings around the world.
