UPGN6-25675-32 Circuit Protection

Circuit Breakers

Circuit breakers are safety devices that automatically switch off electric power in the event of malfunction or short circuit. In industrial and commercial settings, they act as a protective switch to avoid significant damage to expensive equipment and/or endangerment of personnel. When a circuit breaker trips, it interrupts the electric current flowing through a circuit and helps to prevent damage to the electrical system. One particular type of circuit breaker is the UPGN6-25675-32.

UPGN6-25675-32 Application Field

The UPGN6-25675-32 circuit breaker is designed to meet the requirements of the HVAC (heating, ventilation, and air conditioning) industry. The UPGN6-25675-32 can be used for industrial equipment, heating, ventilation, air conditioning, power plants, commercial buildings, and more. This type of circuit breaker is typically found in HVAC systems with single- and three-phase motors, where it helps to reduce the risk of electrical-related accidents and minimize downtime. Additionally, this circuit breaker is used to protect against excess current conditions in electrical systems, including motor overloads and short circuits.

UPGN6-25675-32 Features

The UPGN6-25675-32 has two adjustable trip settings, one for the overload and another for the short circuit trip current. This circuit breaker features a high-rupturing capacity of 8.0 kA, a long time delay, and a maximum voltage rating of 1000V. Additionally, it offers a wide temperature range of - 50°C to + 70°C. It also features an excellent performance in terms of its ability to adjust to the load current. Furthermore, this circuit breaker includes a built-in motor protection circuit.

UPGN6-25675-32 Working Principle

The UPGN6-25675-32 works on a simple principle: it senses faults in the electrical system and disconnects the power to prevent damage or accidents. When a circuit breaker is tripped, the circuit breaker\'s movable contact arm moves from its original ON position to a closed OFF position, thus interrupting the current flow. In the event of an overload, the circuit breaker trips open and stops the current flow. The contact arm must be manually reset after the overload is corrected.

Typically, the circuit breaker uses an electromagnet mechanism to trip the contact arm. A surge in electric current increases the magnetic field created by the electromagnet, which pulls the contact arm onto the switch terminals. These terminals shut off the flow of electricity, thus preventing further damage.

Conclusion

The UPGN6-25675-32 circuit breaker is an ideal choice for HVAC systems requiring single- and three-phase motor protection. With its adjustable trip settings, high-rupturing capacity, and wide temperature range, the UPGN6-25675-32 circuit breaker provides reliable protection against overloads and short circuits. Furthermore, its built-in motor protection circuit helps to reduce the risk of electrical-related accidents and downtime.
