Circuit Breakers

A circuit breaker is a vital device in electrical systems that disconnects the electrical power circuit when it detects an overload or a short circuit. This device is necessary to protect equipment and personnel from harm caused by power surges and breakdowns. The PR11-61-25.0A-XX is a high-performance, low-fault-level circuit breaker used in a variety of applications.

Application Field

The PR11-61-25.0A-XX circuit breaker is designed for general-purpose industrial applications and residential installations. It is capable of breaking motor and transformer circuits for pump protection and lighting protection, in addition to air-conditioning systems, industrial machines, steel mills, and locomotives. The product is also suitable for circuits with power capacities from 10 kW to 250 kW.

Working Principle

The PR11-61-25.0A-XX circuit breaker leverages a combined operation of a mechanical tripping mechanism and a thermal/magnetic trip unit. This trip unit uses a combination of heat and current to detect dangerous conditions that cannot be detected by mechanical tripping alone. The magnetic function ensures that the breaker trips when power exceeds a predefined safe threshold, while the thermal function helps monitor inrush currents which can cause damage to electrical equipment.

The PR11-61-25.0A-XX is designed to provide overcurrent and overload protection. The overcurrent protection monitors and responds to power levels exceeding the pre-set threshold, while the overload protection monitors and responds to current levels that exceed the maximum load rating of the equipment.

The PR11-61-25.0A-XX also incorporates several other features that enhance the protection provided by the breaker. These features include a high-IB trip power, phase-selective trip function, 3-pole wire/wire connection, and shut-off delay capacity. The high-IB trip power prevents any single fault from causing an instantaneous trip in environments where large fault currents may be present. The phase-selective trip feature ensures that any faults present in a single phase are isolated without tripping the entire circuit. The 3-pole wire/wire connection allows the breaker to be used with a 3-phase system. The shut-off delay capacity improves the accuracy of the tripping response since the breaker can be set up to delay shut-off until all three phases have been monitored for overcurrent.

Conclusion

The PR11-61-25.0A-XX circuit breaker offers a combination of features that provide robust and reliable protection for a variety of applications. Its combination of mechanical and thermal/magnetic trip units ensures that it can effectively detect and react to both overcurrent and overload conditions. Additionally, its features such as high-IB trip power, phase-selective trip, 3-pole wire/wire connection, and shut-off delay capacity make it an ideal choice for many industrial and residential applications.
