219-1-4427-1

Circuit Breakers are important safety components for residential and commercial electrical systems. They are designed to protect against electrical problems and prevent potential hazard or fire. The 219-1-4427-1 is a circuit breaker from Siemens designed for residential and commercial applications. In this article, we will discuss the application fields and working principles of the 219-1-4427-1.The 219-1-4427-1 circuit breaker is designed to protect circuits from overloads and short circuits in both residential and commercial settings. Its application field covers everything from single-family homes to larger buildings. This circuit breaker is voltage-independent and can be used in both AC and DC circuits. It is UL and CSA listed and is rated for 120/240V and 60Hz/50Hz.In terms of working principle, the 219-1-4427-1 employs a thermally-activated mechanism. It is built with an internal temperature-sensing element that measures how much current is flowing through the circuit. When the current reaches the rated value or higher, the breaker trips and the power to the circuit is shut off. The thermal-activated mechanism is designed to detect overloads and short circuits. If the overload condition persists for too long, the internal temperature of the winding rises, causing the temperature-sensing element to trigger the breaker. This prevents the wires from burning up or starting a fire. The same mechanism is also triggered in the event of a short circuit.The 219-1-4427-1 is designed for residential and commercial applications and is a reliable and safe circuit breaker. It is rated for up to 120/240V and is thermally-activated, meaning it can detect overloads and short circuits before they become hazardous. Furthermore, it is UL and CSA listed, meaning it has passed stringent safety tests. With an application field covering everything from single family homes to larger buildings, the 219-1-4427-1 is a dependable and reliable choice of circuit breaker.
