Circuit breakers are an important safety device in the electrical distribution system. They are used to detect and protect against unsafe electrical faults. The 219-2-6387-139 circuit breaker is a commonly used circuit breaker in residential and commercial applications. This article will discuss the application field and working principle of the 219-2-6387-139 circuit breaker.

The 219-2-6387-139 circuit breaker is designed to trip and protect against overloads, short circuits, and ground faults. Its rated current is 100A and its rated voltage is 120V. It is designed to protect circuits up to 20-amp in residential and commercial settings. It is also designed to withstand up to 8,000 amps of current during a short circuit. This circuit breaker is UL certified and is UL1077 Recognized, CE Listed, Machine-forge Rated, and suitable for isolation from sources of supply, such as motor overloads, short-circuits, and ground faults.

The working principle of the 219-2-6387-139 circuit breaker is simple. When an overload, short circuit, or ground fault occurs on a protected circuit, the bimetal coil strip inside the circuit breaker will be heated by the increased current. This will cause the coil to deform and activate the tripping mechanism. This will cause the contacts to open, disconnecting the circuit and protecting it from further damage.

The 219-2-6387-139 circuit breaker is most commonly used in residential and commercial applications where safety and protection from overcurrent, short circuits, and ground faults are required. This circuit breaker can be found in numerous applications, such as air-conditioning, refrigeration, lighting systems, pumps, motors, and other types of industrial and commercial machines. It is also often used in home appliances such as ovens, microwaves, and air conditioners.

The 219-2-6387-139 circuit breaker is designed to provide protection and safety in residential and commercial applications. Its reliable design and easy installation make it a preferred choice among electricians and engineers. Its simple working principle ensures fast and efficient protection from overcurrent,short circuits, and ground faults, providing the added safety and security that is needed by electricians, engineers, and homeowners.
