CR11-52-5.00A-R06CH-V

Circuit breakers, also known as Circuit breakers, are devices designed to interrupt an electrical circuit when an abnormally high current arises, usually due to a fault or overloading. The CR11-52-5.00A-R06CH-V, a circuit breaker manufactured by ABB, is designed for various industrial applications.

Application Field

The CR11-52-5.00A-R06CH-V is designed for line/load protection and motor control applications in industries such as petrochemicals, offshore platforms, marine, paper and pulp, nuclear and power generation. The maximum AC rating of the breaker is 690 V and 100 A.

Working Principle

The CR11-52-5.00A-R06CH-V circuit breaker works on the principle of thermal-magnetic protection. When the temperature or current in the circuit rises above the predetermined threshold, a bimetal strip in the breaker bends and trips a disconnect device that opens the circuit. The disconnect device is also connected to a coil and when an overcurrent occurs, the coil creates a magnetic field that pulls the trip lever and opens the circuit.

The CR11-52-5.00A-R06CH-V also features an adjustable trip mechanism, which allows for precise control over trip times and current settings. The circuit breaker also has a manual reset, which can be used to reset the breaker in case of a fault. The CR11-52-5.00A-R06CH-V also has various protective functions, such as overvoltage and under voltage protection, over-temperature and over-current protection.

Conclusion

The CR11-52-5.00A-R06CH-V is an effective and reliable circuit breaker designed by ABB for applications in industries such as petrochemicals, offshore platforms, marine, paper and pulp, nuclear and power generation. It works on the principle of thermal-magnetic protection and contains adjustable trip mechanisms, manual reset and various protective functions.
