Circuit breakers are electrical protective devices designed to interrupt or inhibit the flow of excessive electric current. These devices are designed to operate by sensing the current flowing through them, and if it exceeds the predetermined level (the nominal current), they open the circuit, thereby breaking the connection. The CR11-52F-20.0A-R01CV-V is a circuit breaker designed to protect the circuit from overcurrents while allowing normal current flows.

The CR11-52F-20.0A-R01CV-V circuit breaker features a manual reset design, meaning that when the breaker is opened, it requires manual operation to restore power. This helps to protect the circuit from unnecessary trips, as resetting the breaker requires someone to physically remove the device from the circuit and reset it. The manual reset design eliminates the need for additional relays, making the CR11-52F-20.0A-R01CV-V an economical solution for overcurrent protection.

The CR11-52F-20.0A-R01CV-V circuit breaker is designed for use with circuit installations in residential and commercial applications. It can be used in branch lines, industrial applications, motor control, and other electric circuits. It is certified by Underwriters Laboratories ("UL") as both a Type 1 and Type 2 breaker.

The working principle of the CR11-52F-20.0A-R01CV-V circuit breaker is relatively simple. The excessive electric current, when detected by the device, causes an internal temperature threshold to be exceeded and the bimetal strip within the breaker to expand. This causes a spring-loaded switch to engage and trip the breaker, interrupting the electric current. The spring-loaded switch then requires manual resetting to restore power to the circuit.

The CR11-52F-20.0A-R01CV-V circuit breaker offers high interrupting ratings of 200Amps at 240V, and 10kA at 240V. This makes it ideal for residential and industrial applications. For example, it can be used to protect feeders, services, and motor circuits from over current. It accommodates to both copper and aluminum wire, and meets or exceeds all UL requirements and industry standards. Additionally, the slim profile and lightweight design allow for easy and flexible installation.

In summary, the CR11-52F-20.0A-R01CV-V circuit breaker is an economical and reliable solution for overcurrent protection in residential and commercial applications. Its manual reset design eliminates the need for additional relays and its slim, lightweight design allows for easy and flexible installation. It is UL certified to meet or exceed all industry standards, and it offers high interrupting ratings for superior current-control protection.
