Circuit breakers are an essential component of any electrical system. The UPL1-1-72-503 is a special type of circuit breaker designed for use in residential, commercial, and industrial applications. It is designed to protect equipment and wiring from short-circuit currents, as well as isolating circuits from each other. This article will discuss the application field and working principle of the UPL1-1-72-503 circuit breaker.

The UPL1-1-72-503 circuit breaker is designed to be used in both residential and commercial applications. It is UL listed for use in 120/240V single-phase and 120/208V three-phase systems. The circuit breaker is rated for a maximum of 150 amps, making it suitable for larger areas and applications which require more power. This circuit breaker is also UL listed for both overload and short-circuit protection.

The UPL1-1-72-503 circuit breaker uses a thermal-magnetic trip mechanism for over-current protection. This type of mechanism uses both thermal and magnetic elements to detect over-current situations. The thermal element detects slow-developing, high-temperature faults which would normally take longer to trip the circuit breaker than magnetic trip action. The magnetic element is designed to detect higher current, short-circuit applications, which require a faster response time.

The UPL1-1-72-503 circuit breaker also features a selectable trip range. This means that it can be set for either a lower rated current of 15-100 amps or a higher rated current of 100-150 amps. This provides flexibility in terms of over-current protection for different applications. For example, if the circuit breaker is being used in a commercial setting, it can be set to the higher trip range for maximum protection. On the other hand, if it is used in a residential setting, it can be set for the lower trip range, in order to avoid unnecessary tripping.

In addition, the UPL1-1-72-503 circuit breaker features a quick-make, quick-break design. This means that it trips fast, which reduces the potential for damage due to power disruptions. The circuit breaker can also be reset quickly, making it easy to restore service after a trip. The circuit breaker also features a visible manual trip lever, so it can be tested or tripped manually.

Finally, the UPL1-1-72-503 circuit breaker is designed to be corrosion-resistant and tamper-resistant. It is designed to be both durable and reliable in its operation, providing years of reliable service. The circuit breaker is also UL listed, so it meets all safety standards.

In conclusion, the UPL1-1-72-503 circuit breaker is designed for residential, commercial, and industrial applications. It features a thermal-magnetic trip mechanism, selectable trip range, quick-make, quick-break design, and a visible manual trip lever. The circuit breaker is corrosion-resistant, tamper-resistant, and UL listed for safety. All these features make the UPL1-1-72-503 circuit breaker an ideal choice for any application requiring reliable over-current protection.
