Circuit breakers are essential to power delivery systems, as they help prevent system overloads and establish a certain level of safety. PR21-2-20.0A-XX-V is a type of circuit breaker that can protect circuits from abnormal overload and short circuit currents. This section will go into detail regarding the applications and working principle of this type of circuit breaker.

Applications

The PR21-2-20.0A-XX-V circuit breaker is designed for residential, commercial, and industrial applications. It can be used for both AC and DC circuits for protection of electric motors, transformers, and other related equipment. The circuit breaker is available in 1, 2, and 3 pole configurations and is rated for 240 VAC and 480 VAC systems. It is suitable for PANEL- or BUS- mounted installations.

The circuit breaker is UL, CSA, and CE approved, and meets IEC947-2, UL489 and UL508 standards. It has a built-in thermal and magnetic trip option, as well as overvoltage and undervoltage protection. Its current rating of 20A makes it ideal for applications that require lower amp ratings.

Working Principle

The PR21-2-20.0A-XX-V circuit breaker uses a bimetallic strip mechanism to detect overloads and shorts. When an electric current flowing through the breaker passes a certain threshold, the bimetallic strip bends and trips the breaker. This causes the circuit breaker to open, which interrupts the flow of electricity and prevents any further damage.

The circuit breaker also uses a magnetic trip mechanism to detect short circuits. When a sudden high current is detected, the circuit breaker trips almost instantaneously and shuts off the power. This protects the system by limiting the amount of time it takes to stop the high current. It also ensures that there is no additional damage to the equipment.

The PR21-2-20.0A-XX-V circuit breaker also has a manual reset option. This allows the user to reset the circuit breaker after a fault and restore power to the circuit. It also provides a visual indication when the breaker has been tripped. This helps the user identify the problem and determine if repairs or replacements are necessary.

Conclusion

The PR21-2-20.0A-XX-V circuit breaker is designed for residential, commercial, and industrial applications. It has a current rating of 20A and is UL, CSA, and CE approved. The breaker uses a bimetallic strip and magnetic trip mechanism to detect overloads and shorts. It also has a manual reset option and provides a visual indication when the breaker is tripped. The circuit breaker ensures the safety of circuits and helps prevent system overloads.
