Circuit breakers are one of the most important components of any electrical system. They are designed to protect electrical devices and circuits from overloads and short circuits. The 219-3-34680-969 circuit breaker is a two-pole, single-phase circuit breaker with thermal-magnetic protection. It is capable of handling currents up to 630A at 480VAC and is one of the most commonly used types of circuit breakers.

The application field of the 219-3-34680-969 Circuit Breaker is the control and management of electrical power circuits in residential, commercial, and industrial facilities. It is typically used in applications where medium to high current levels are present. It is also common in circuit breakers used in sub-stations and motor control centers.

The working principle of the 219-3-34680-969 Circuit Breaker is based on the principle of thermal-magnetic protection. The device contains a bimetallic element and a magnetic trip element. When the current exceeds the set limit, the temperature of the bimetallic element increases. This causes the metal to expand, which in turn trips the magnetic trip element and interrupts the circuit.

In addition, the 219-3-34680-969 Circuit Breaker also includes a thermal/magnetic reset switch. When the current is low, the switch will reset and the circuit breaker will function normally. This reset mechanism allows the circuit breaker to reset itself automatically after a short circuit or overload has been detected.

The 219-3-34680-969 Circuit Breaker is an essential element of any electrical system. It provides protection from overloads and short circuits, ensuring the safety of all electrical devices connected to the system. It is widely used in residential, commercial, and industrial applications. Its thermal-magnetic protection principle and reset switch make it one of the most reliable circuit breakers available.
