Circuit breakers play a vital role in electrical circuits, providing protection against potential damage due to overcurrent or short circuit conditions. UPG4-34971-5 circuit breaker is an advanced product that is designed for both AC and DC applications. It is designed to meet UL489B and EN60947-2 standards.

The UPG4-34971-5 circuit breaker operates on the principle of thermal-magnetic protection. When a fault current occurs, the magnetic force created by the current causes a tripping mechanism to be activated, which then opens the contacts of the circuit breaker. This interruption of the circuit trips the breaker, thereby protecting the electrical circuit.

The UPG4-34971-5 circuit breaker is designed for a wide range of industrial applications. It can be used in various fields including electrical engineering, shipbuilding, automation, railway and other industrial sectors. It is suitable for residential, industrial, commercial, mobile and generator applications.

This circuit breaker is equipped with a variety of features that make it ideal for use in a wide range of applications. It has a wide range of current ratings, including 125Amps and 250Amps. It is also designed with a current limiting feature, which helps to prevent damage caused by short circuit currents. Additionally, it is equipped with a sensitive overcurrent protection which trips the breaker when it senses a high-level fault current.

The UPG4-34971-5 circuit breaker also offers long life and reliability. It is constructed with a heat-resistant thermoplastic housing which is impervious to most industrial chemicals, and it is RoHS-2 compliant. Its UL489B-approved contacts are designed to withstand high temperatures, making it an ideal choice for applications where temperatures can exceed 200 degrees Celsius.

In addition, the UPG4-34971-5 circuit breaker has a high-quality trip unit that is designed to provide precise calibration and reset times. This enables it to react quickly and accurately when the fault current exceeds the specified protection level. The trip unit also has an adjustable time delay, allowing users to customize the protector according to their specific needs.

The UPG4-34971-5 circuit breaker is a reliable and versatile product that can be used in a wide variety of industrial applications. It provides efficient protection against overcurrent and short circuit conditions to help protect electrical circuits from potential damage. With its wide range of features and its RoHS-2 compliance, the UPG4-34971-5 circuit breaker is an excellent choice for industrial applications.
