Introduction

The UPGF6-31106-25 is a circuit breaker manufactured by Corning. It is designed for the European market as the European National Electrical Code (ENEC) requires different specifications for circuit breakers than the U.S. based National & Electrical Code (NEC). UPGF6-31106-25 circuit breakers provide electrical protection for motor-driven and static equipment. It is a single pole, manually reset and adjustable type of circuit breaker.

Application Field

UPGF6-31106-25 circuit breakers are suitable for applications in which the current and the voltage rating are not normally higher than a nominal frequency of 50Hz or 60Hz. This model enables the distribution of power in single or three-phase circuits as motor protection and protection of other electrical equipment. It can be used in a variety of environments, including residential, commercial, industrial and outdoor applications. They can be used in switchboards, motor control centers and other control panels.

Working Principle

The working principle of the UPGF6-31106-25 circuit breaker is based on the thermal-magnetic trip characteristics. The breaker has two overload elements, namely a fixed resistor connected in series and a thermal element which is connected in parallel. When the current in the circuit exceeds the set trip point, the thermal element absorbs the excess current, heating it up and causing it to expand. The expanding thermal element breaks the circuit and the power to the load is interrupted.

The magnetic trip element works differently. When an excessive current flows through the circuit, it generates a magnetic field. This magnetic field interacts with the fixed resistor and causes it to vibrate. The vibration triggers a breaker trip, opening the circuit and protecting your equipment from damage.

Conclusion

The UPGF6-31106-25 circuit breaker is an ideal choice for the European market due to its ENEC compliance. With its thermal and magnetic trip principles, this breaker provides reliable protection to motor-driven and static equipment while operating in various environments. It is a single pole, manually reset and adjustable type of circuit breaker suitable for a wide variety of applications.
