UPGF66-30513-11 Circuit Protection

Circuit breakers are an essential part of electrical systems, providing protection against overloads and short circuits. The UPGF66-30513-11 is a type of circuit breaker designed for DC applications. It offers reliable protection in a compact and easy to install package. This article will discuss the application field and working principle of the UPGF66-30513-11.

Application Field

The UPGF66-30513-11 is a 24V DC circuit breaker that is designed for use in low voltage DC circuits. It is rated up to 25A, making it suitable for applications such as solar power systems, electric vehicles, electromobility applications and industrial control systems. It is also suitable for use in hazardous areas, as it complies with ATEX certification.

The UPGF66-30513-11 comes with an integrated thermal protection device, which makes it suitable for applications where a high level of protection against overloads is required. It is also resistant to shock and vibration, so it can be used in hostile environments. Finally, it has a wide operating temperature range of -25°C to +60°C.

Working Principle

The UPGF66-30513-11 is a motor-driven thermal-magnetic circuit breaker. This means that it works by combining two protection systems: a thermal protection system and a magnetic trip system. The thermal system works by monitoring the temperature of the breaker, and trips if the temperature rises too high. This protects the breaker from overloads and short circuits. The magnetic system works by using a magnetic field to detect and trip the breaker when there is an excessive current flowing through it. This provides reliable protection against short circuits.

The UPGF66-30513-11 has an adjustable trip current setting, which allows the user to adjust the current at which the breaker trips. This can be used to customize the protection provided by the breaker. It also has a “short-time pick-up” setting, which allows the breaker to remain closed for a short time after a short circuit, allowing the fault current to be safely reduced without causing further damage.

The UPGF66-30513-11 is an efficient and reliable protection device that is designed to provide reliable protection against overloads and short circuits. Its integrated thermal protection and adjustable trip current settings make it suitable for a wide range of application fields, including solar power systems, electric vehicles and industrial control systems.
