It also features adjustable tripping characteristics, allowing the user to customize the thermal and short circuit tripping behavior. It also includes an adjustable instantaneous tripping range, allowing the user to set the tripping current.
Applications
The 229G-4-32087-5 is designed for use in high-voltage power distribution switchboards. It is suitable for use in both residential and industrial applications, as well as the telecom and electronics sectors. Its small form factor makes it especially well suited for smaller switchboards. Thanks to its adjustable settings and wide range of available ratings, the 229G-4-32087-5 is capable of safely meeting the diverse needs of a variety of applications.
Working Principle
The 229G-4-32087-5 circuit breaker utilizes a thermal-magnetic tripping mechanism, which is designed to detect and respond to both over-current and over-temperature events. When an over-temperature event occurs, such as an overload, the breaker trips using both thermal and magnetic principles. The breaker uses a bimetallic strip, which is heated by the current and expands, allowing it to trip the circuit. It also uses magnets to detect severe overloads and respond by tripping the circuit almost instantaneously.
Conclusion
The 229G-4-32087-5 circuit breaker is designed for use in high-voltage power distribution switchboards. It is rated for voltages up to 550V, and current ratings from 300 to 2500 amps. Its small size and adjustable settings make it suitable for a wide range of applications. Its thermal-magnetic tripping mechanism uses a bi-metallic strip and magnets to detect and respond to over-current and over-temperature events.
