Circuit Breakers

A circuit breaker is an electrical device used to protect an electrical circuit from damage caused by excess current from an overload or short circuit. The PR11-1-25.0A-XX-V is one type of circuit breaker that is designed to be used in residential, commercial, and industrial applications. In this article, we\'ll discuss the application field and working principle of this particular model of circuit breaker.

Application Field

The PR11-1-25.0A-XX-V is a 25 ampere multi-pole residential circuit breaker. This type of circuit breaker is suitable for use in residential, commercial and industrial installations as it is designed to meet UL 1077 standards for household circuit breakers. This type of circuit breaker is designed for use in AC systems in which the voltage does not exceed 240 volts with a maximum frequency of 60 Hertz. This type of circuit breaker is suitable for use with most wiring systems, including single-phase and multi-phase systems.

Working Principle

The working principle of the PR11-1-25.0A-XX-V circuit breaker is relatively straightforward. It operates using a thermal-magnetic trip unit, which is composed of both thermal and magnetic components. The thermal component senses the temperature of the current in the circuit and trips when the temperature reaches a preset level. The magnetic component senses changes in the current in the circuit and trips when the current reaches a preset level. The tripping action of the breaker is triggered either by a rapid increase in current or a sustained level of current higher than the rated value. Once the circuit breaker has tripped, it can be reset by the operating switch.

The PR11-1-25.0A-XX-V circuit breaker also has a manual trip test button, which allows users to test the operation of the circuit breaker. Test operation can help users identify problems such as current overloads, short circuits, and other electrical issues. The manual trip test button also saves time and money, as it allows users to quickly diagnose problems and take corrective measures.

The PR11-1-25.0A-XX-V is designed for both residential and commercial applications, and is an ideal choice for a variety of electrical system scenarios. It is easy to install, requires minimal maintenance, and is highly reliable. It features a self-locking mechanism, which prevents the circuit breaker from being accidentally tripped by outside forces. The PR11-1-25.0A-XX-V is also UL Listed, meaning it meets the safety standards set by Underwriters Laboratories.

Conclusion

The PR11-1-25.0A-XX-V is an excellent choice for residential, commercial, and industrial applications. It is designed to meet the highest standards of safety and reliability, and is easy to install and maintain. This circuit breaker is designed to protect against excess current from both overloads and short circuits, and it also features a manual trip test button for quickly identifying electrical issues. In short, the PR11-1-25.0A-XX-V is a great choice for any application requiring circuit breaker protection.
