Circuit breakers are essential electrical safety devices that serve to stop circuits in the case of an overload or a short circuit. The 219-3-30497-1 model is a type of circuit breaker, which is primarily used in low-voltage applications that require smaller, more reliable circuit protection. In this article, we’ll explore the application field and working principle of this specific circuit breaker.

Application Field

The 219-3-30497-1 circuit breaker is primarily designed for use in a range of low-voltage applications, such as residential and commercial buildings, malls, electric busses, and other low-voltage applications. This circuit breaker is suitable for applications that require accurate and reliable circuit protection but are not suitable for heavy-duty industrial applications. The low-voltage voltage range of this circuit breaker is 0–250 VAC, with a maximum current of 25 amperes.

Working Principle

The 219-3-30497-1 circuit breaker utilizes a thermal-magnetic tripping system. This system uses a combination of thermal and magnetic release mechanisms to detect overload or short-circuit conditions. The thermal element is responsible for detecting steady-state and low-level overcurrent conditions, while the magnetic element is responsible for detecting high-level overcurrent and short-circuit conditions. The thermal element is based on bimetallic strips that become heated up as the current passes through them, while the magnetic element uses a solenoid system to trip the breaker.

When an overload or short-circuit is detected, the magnetic and/or thermal elements actuate the switch which opens the circuit. They will also actively trip in order to protect the connected circuit from being damaged by excessive current. Once the fault or overload has been cleared, the circuit breaker can be reset manually and the circuit will be restored.

The 219-3-30497-1 circuit breaker is designed to be used in applications where reliable circuit protection is required but space is limited, such as small electric busses or residential and commercial buildings. It provides reliable protection with its thermal-magnetic tripping system, and its small form factor allows for easy installation in almost any application.
