Circuit breakers are essential components of electrical safety systems designed to protect both people and devices against power surges or short circuits. The UPGN11-22599-1, primarily used in industrial applications, is a two-pole trip-free thermal-magnetic circuit breaker with adjustable overload and short-circuit characteristics.

Application Field

This circuit breaker is typically used in industrial machinery, building control systems, and automation or process instrumentation. It provides reliable overload and short-circuit protection for electric motors and their associated control components, such as relays, contactors, PLCs, and other devices in industrial applications where large amounts of current are handled. This device is suitable for both AC and DC circuits, and its versatility makes it ideal for many applications in industrial settings.

Working Principle

The UPGN11-22599-1 works by combining thermal and magnetic elements to provide reliable overload and short-circuit protection for power and control circuits. In normal operation, the thermal element prevents the circuit from tripping in the event of an overload.

If an overload reaches a predetermined limit, the thermal element trips and the magnetic element takes over, tripping the circuit in the event of a short circuit. This ensures that the circuit is not damaged, and the user is protected from any potential harm. The adjustable overload characteristics make it easy to tailor the UPGN11-22599-1 to the specific needs of the application.

In summary, the UPGN11-22599-1 is a two-pole, trip-free thermal-magnetic circuit breaker with adjustable overload and short-circuit characteristics. It is versatile and suitable for both AC and DC circuits, making it ideal for industrial applications where large amounts of current are handled. Its adjustable overload characteristics provide reliable over-temperature protection for electric motors and their associated control components, while its magnetic element provides accurate short-circuit protection.
