PR11-4-10.0A-XX-V

Circuit Breakers provide a means for protecting circuits and systems from damage due to overloads or short circuit conditions. The PR11-4-10.0A-XX-V is a circuit breaker used to protect equipment and personnel from potential hazards posed by electrical overloads. This device is designed to provide an efficient and economical way to protect against short circuit and overload conditions. In this article, the application field and working principle of the PR11-4-10.0A-XX-V will be discussed.

Application Field

The PR11-4-10.0A-XX-V is a molded-case circuit breaker (MCCB) that is suitable for use in industrial, commercial, and residential applications. It is designed to provide short-circuit protection and overload protection for wide range of circuits and different types of loads. It is available in two frame sizes, 4 and 6 poles, and two voltage ratings, 240 and 480 volts. The device can be used for protection against over-current, overload and non-stop applications, as well as motor control applications. The device is designed with a trip curve that is adjustable to provide various levels of current protection and an adjustable overload setting to ensure that the selected level of protection is provided for the application.

Working Principle

The PR11-4-10.0A-XX-V utilizes a thermal-magnetic operating principle. This principle utilizes the combination of heat and magnetism to trip the breaker. When the device is subjected to over-current conditions, it will cause the internal piece of ferromagnetic material to become magnetized and pull the trip bar, which will in turn trip the circuit breaker. When the current levels return to normal, the magnetism dissipates and the internal pieces of ferromagnetic material re-align and the breaker is reset.The device also features an adjustable overload setting, which allows the user to set the trip point of the device. When the rated current reaches this point, the thermal-magnetic operating principle is utilized, resulting in the circuit breaker tripping due to the over-current condition. This feature provides protection against motor overloading, as well as providing an efficient way to protect against short circuit conditions.The PR11-4-10.0A-XX-V also has an isolation feature, which allows the user to disconnect the circuit breaker from the power supply if necessary. This feature can be used to ensure personnel safety while conducting maintenance or repairs on the circuit.

Conclusion

The PR11-4-10.0A-XX-V is a molded-case circuit breaker (MCCB) that is suitable for use in industrial, commercial, and residential applications. It is designed with a thermal-magnetic operating principle and an adjustable overload setting to provide various levels of current and overload protection. The device also features an isolation feature that allows the user to safely disconnect the device from the power supply if necessary. This device provides an efficient and economical way to protect equipment and personnel from potential hazards posed by electrical overloads.
