Circuit Breakers

Circuit breakers are electrical switching devices designed to interrupt current flow during an abnormal or fault condition. They provide over-current protection for electrical components, systems, and networks by providing a physical disconnect of the circuit, preventing further damage and protecting electrical equipment from serious damage or destruction. The IUG21-1REG4-37510-15 circuit breaker is specially designed to provide over-current protection for electrical components in the industrial control and automation industry.

Application Field and Working Principle of IUG21-1REG4-37510-15 Circuit Breaker

Application Field: The IUG21-1REG4-37510-15 is a 3-pole, NEMA rated framing circuit breaker that is primarily used for the protection of motor circuits in the industrial control and automation industry. The IUG21-1REG4-37510-15 can also be used in applications that require alternating current up to 600 volts AC, and can be used in both three-phase and single-phase applications. It is suitable for use in circuits that require up to 30 hp.

Working Principle: The IUG21-1REG4-37510-15 uses mechanical contacts to open or close circuits as needed. The circuit breaker has an operating mechanism that is triggered either manually or automatically when an over-current condition is detected. When the current reaches a set threshold, the operating mechanism is tripped and the electrical contacts in the circuit breaker are opened. This interrupts the circuit, resulting in an open circuit. The contacts can then be reset when the fault condition has been cleared.

The IUG21-1REG4-37510-15 circuit breaker also offers a number of additional functions, such as short-circuit protection, overload protection, and reverse-polarity protection. It is also equipped with a thermal-magnetic releasing device, which provides additional protection against high overloads and short circuits. The thermal-magnetic releasing device senses the temperature of the device and trips the circuit breaker in the event of excessive temperature. Lastly, the circuit breaker also has an instantaneous overload protection trip, which is designed to protect the device and the circuit if an overload occurs.

The IUG21-1REG4-37510-15 circuit breaker is designed to provide reliable and safe protection against short-circuits, ground faults, and other dangerous conditions. It is used in a variety of industrial applications and is suitable for applications that require a high level of protection from over-currents. It is a reliable and versatile product that is designed to provide years of reliable service.
