Circuit breakers are essential components in cabling systems, providing protection against overcurrents, undervoltage, and overvoltage conditions that can cause significant damage or even fire. The PP11-61F-25.0A-36371-4 is a common circuit breaker used in a variety of applications. This article will discuss the application fields of this circuit breaker and its working principle.

Application Fields

The PP11-61F-25.0A-36371-4 is a triple pole circuit breaker with a voltage rating of 250 volts AC. It is a UL listed product, conforms to IEC 60947-2, and meets the requirements of Commonwealth of Australia AS/NZS 60947.2. This breaker is designed for a variety of applications, including:

• Residential applications-This type of circuit breaker is used in residential homes to protect lighting and appliance circuits.
• Commercial buildings-A PP11-61F-25.0A-36371-4 circuit breaker is suitable for the majority of commercial buildings that require the use of breakers to protect a circuit from overloads or short circuits.
• Institutional buildings-Hospitals, schools, and other large institutional facilities often require circuit breakers that are up to the task of protecting the electrical systems used in these buildings.

The PP11-61F-25.0A-36371-4 is rated for a maximum breaking capacity of 25.0A and a rated operating current of 25.0A. It is suitable for use in both single- and three-phase circuits.

Working Principle

The PP11-61F-25.0A-36371-4 employs an electromagnetic operating mechanism to operate and reset the breaker. The mechanism consists of a trip arm, an electromagnet, and a manual reset button. When the breaker is tripped, the trip arm is pulled in by the electromagnet, allowing the contacts to open and disconnect the circuit. To reset the breaker, the manual reset button must be pressed in. This action releases the electromagnet and the trip arm is pushed back, allowing the contacts to close and reconnect the circuit.

The PP11-61F-25.0A-36371-4 circuit breaker features a thermal-magnetic operating system that monitors both the heat buildup caused by excessive current and the magnetic force produced by an overload or short circuit. The breaker can be manually tripped by pressing the test/reset button, or it can be electronically tripped by an overload device.

Conclusion

The PP11-61F-25.0A-36371-4 circuit breaker is a UL listed product with a maximum breaking capacity of 25.0A and a rated operating current of 25.0A. It is suitable for residential, commercial, and institutional applications and has a thermal-magnetic operating system that can detect overloads or short circuits. The breaker employs an electromagnetic operating mechanism for its operation and resetting.
