Circuit breakers are essential components of any electrical power system, providing reliable protection against overloads and faults. The UPG66-24257-14 Breaker is a suitable choice for the electrical power system due to its reliable performance and versatility. This article examines the application field and working principle of the UPG66-24257-14 Breaker.

The UPG66-24257-14 Breaker is rated up to 400A at 480VAC and is a UL 489 listed 3-pole type. It is a suitable choice for electrical power systems such as residential, commercial, industrial, and outdoor applications. This breaker has several features which make it an ideal choice for these applications. The breaker features trip-free operation, a quick-make, quick-break mechanism, high interrupting capacity and current limiting options. Additionally, the breaker is easy to install, thanks to its plug-in design, and can be customised with several accessories, including power fuses. The breaker also includes a ground fault indicator and a tamper-proof design.

The UPG66-24257-14 Breaker has a unique working principle which enables it to perform reliably and safely. This breaker operates on the principle of an electromagnetic force, which varies with the current passing through it. When the current in the circuit exceeds the rated current, a magnetic force proportional to the increase in current is generated. This magnetic force trips the internal mechanism of the breaker, which trips the circuit and prevents it from overloading. The magnetic force also causes the breaker to automatically reset when the current passes normal operating levels.

The UPG66-24257-14 Breaker also has several distinguishing features which set it apart from other circuit breakers. The breaker is designed with a hydraulic-magnetic mechanism which helps reduce wear and tear of the operating parts, thereby increasing the life of the breaker. In addition, the breaker is factory calibrated to trip accurately and is designed with an anti-pumping feature that prevents the breaker from being re-plugged until the current returns to a normal level. The breaker also features a selectable lockout/tag-out feature which prevents unauthorized operation and enhances safety.

Overall, the UPG66-24257-14 Breaker is a suitable choice for a variety of electrical power applications due to its reliability, performance, versatility, and safety features. The breaker is rated up to 400A and is UL 489 listed. It features trip-free operation and a quick-make, quick-break mechanism. Additionally, the breaker is easy to install and can be customised with several accessories. The breaker also has a unique working principle which operates on the principle of an electromagnetic force. Finally, the breaker features numerous distinguishing features, including a hydraulic-magnetic mechanism, anti-pumping feature, selectable lockout/tag-out feature, and factory calibration.
