CR11-51F-30.0A-R01IV-V

Circuit breakers are important electrical safety devices that protect circuits and personnel from damage due to overload or short circuit conditions by quickly interrupting the flow of electricity. A CR11-51F-30.0A-R01IV-V is a type of circuit breaker designed for high-current applications and provides a safe and reliable means of protection. The device contains several components that work together to detect a fault, initiate circuit intervention, and reset. This article will discuss the application field and working principle of the CR11-51F-30.0A-R01IV-V circuit breaker.

The CR11-51F-30.0A-R01IV-V is specifically designed to handle high levels of current and protect medium voltage applications, such as industrial power systems, epicyclic motors and transformers. The device includes a manual trip element and a thermal-magnetic trip element, both of which provide reliable overcurrent protection and rapid interruption of the circuit. The manual trip element comprises a hinged housing containing a spring-loaded trip bar that is connected to a toggle arm. The toggle arm is triggered by a magnetic field generated by the current. The thermal-magnetic trip element is designed to detect both overload and short circuit conditions by sensing the temperature of the circuit and the current flow.

When a fault is detected, the CR11-51F-30.0A-R01IV-V circuit breaker immediately opens the circuit, protecting the circuit and personnel from damage. Upon opening the circuit, an indicator light on the device illuminates, indicating the fault and the need to reset the circuit breaker. The device can be reset manually by pushing the toggle arm back into position, or automatically if the fault has been cleared.

The CR11-51F-30.0A-R01IV-V circuit breaker is a reliable, robust device capable of providing protection for industrial power systems, epicyclic motors and transformers. Its manual and thermal-magnetic trip elements quickly detect and open the circuit when an overload or short circuit condition is detected, while its resetting capabilities make it easy to restore power in the absence of a fault.
