What is a UPG666-1359-2 Circuit Breaker?

The UPG666-1359-2 circuit breaker is an electronic protective device designed to protect electrical systems from short-circuits and overloads. It is a three-phase, air-core, power circuit breaker that combines thermal-magnetic trip protection, surge suppression, and variable trip settings for custom protection. The UPG666-1359-2 can be used in a wide range of residential, commercial, and industrial applications, including those that require sensitive electronic systems.

Application Field

The UPG666-1359-2 is suitable for circuit protection of high power, motor and lighting load in three-phase AC power distribution circuits. Its rated current can range from 6 to 150 amperes, and its rated voltage can range from 120-480 volts AC. This circuit breaker can be installed in domestic and industrial applications, such as power supplies, circuit control, etc.

Working Principle

As a current-limiting device, the UPG666-1359-2 is designed to allow limited current flow in the event of an overcurrent or short circuit. In normal operation, it maintains current levels to protect the circuits without tripping. The UPG666-1359-2 is equipped with both thermal and magnetic tripping devices. The thermal tripping device is designed to respond to overloads and ‘cold load’ conditions. The magnetic tripping device is designed to respond to short-circuits. The thermal and magnetic tripping devices can be set so that the UPG666-1359-2 responds to current levels that are higher than the operating current. When the set level is exceeded, the tripping device trips, which cuts off the power supply in less than 10 milliseconds, breaking the circuit and protecting the system. The UPG666-1359-2 is equipped with an adjustable surge suppression device that reacts to voltage changes. This is especially useful for protecting equipment that is susceptible to surges.

Conclusion

The UPG666-1359-2 is a versatile and reliable circuit breaker that can provide optimal protection for residential, commercial, and industrial applications. Its thermal and magnetic trip devices provide superior protection for sensitive equipment against overloads and short-circuits, while its adjustable surge suppression device provides further protection against dangerous surges.
