Circuit breakers are very common parts of electrical systems today. The UPG66-22090-1 is a particular type of circuit breaker that is designed for a variety of applications and has a number of unique features. This article will discuss the application field and working principle of the UPG66-22090-1 circuit breaker.

Application Field

The UPG66-22090-1 circuit breaker is designed for both indoor and outdoor applications. It is ideal for use in warehouses, factories, office buildings, and other industrial locations where the environment can fluctuate from hot to cold. It is also suitable for use in marine environments, as it is protected by a stainless steel enclosure and has corrosion-resistant contacts.

The UPG66-22090-1 is suitable for use in all types of AC circuits, ranging from 50V to 440V with a current rating of 150A. It is also suitable for use in a variety of DC circuits, such as solar systems, automotive systems, and other low voltage DC systems.

Working Principle

The UPG66-22090-1 circuit breaker is designed to protect a circuit from damage caused by an overcurrent. To do this, the circuit breaker has two primary components: the trip unit and the thermal element. The trip unit is the part of the device that senses the current and trips when the current exceeds the predetermined threshold. The thermal element is a temperature sensing device that is designed to trip the breaker when the temperature of the circuit reaches a certain point.

When the circuit exceeds it\'s rated current, the trip unit senses the overcurrent and trips the breaker. This interrupts the flow of electricity and protects the circuit. The thermal element will also trip the breaker if the temperature of the circuit reaches a certain level. This prevents the circuit from overheating, which can cause permanent damage.

The UPG66-22090-1 is designed to provide reliable and accurate protection to an electrical system. It features both manual and automatic reset, allowing the user to reset the breaker without having to power down the system. The device also features thermal trip compensation, which helps to ensure that the breaker trips at the correct temperature even if the ambient temperature changes.

Conclusion

The UPG66-22090-1 circuit breaker is a versatile device that is suitable for a variety of applications. It is designed to provide reliable protection against overcurrent and overheating to ensure the safety of an electrical system. The working principle of the device is straightforward, and it can be easily reset without having to power down the system.
