Circuit Breakers are an essential component for low-voltage electrical systems. They protect the circuit from overload or short circuit conditions, by providing a quick and reliable way to cut off power in the event of a fault. The CB221-20 is a modern type of circuit breaker designed to be used in high performance applications.

The CB221-20 is designed to handle a wide range of current ratings, from 2A to 20A. It is capable of breaking the circuit at a set current value, even if the load is unbalanced. The device is also designed to detect and interrupt any fault currents, such as those generated by a short circuit or arc fault, without the need for manual intervention.

The CB221-20 is suitable for use in a variety of applications, including residential, commercial and industrial installations. It is particularly well-suited for use in sensitive areas such as hospital operating rooms, where even the slightest disruption of power can be hazardous. The CB221-20 is also ideal for use in mobile applications, such as trucks and recreational vehicles, where the circuit breaker can help protect both the vehicle and its occupants from hazardous short-circuits.

The CB221-20 is a two-pole, two-wire device, meaning it is capable of connecting to two separate wires or circuits. It is typically installed between the power source and the load, and interposed in the circuit to provide protection against overcurrent, short circuits, ground faults, and other potentially hazardous conditions. The CB221-20 uses a thermal-magnetic trip unit, which is designed to detect any abnormal current or over-current conditions, and to trip the device when the threshold is exceeded.

When the CB221-20 detects an overcurrent condition, it sends a signal to the tripper mechanism, which trips the device and interrupts the circuit connection. The tripper mechanism can be reset manually, allowing it to be re-energized, or it can be reset automatically by the thermal-magnetic trip unit. The CB221-20 is also equipped with a visual indicator, which displays a green light when the device is functioning correctly, and a red light when there is an overcurrent or short circuit condition.

In addition to providing a reliable form of overcurrent protection, the CB221-20 has several other advantages. It is a robust and reliable device that is simple to install, and it requires very little maintenance. The device is also relatively easy to reset, allowing it to be quickly re-energized in the event of a fault. In addition, the CB221-20 is designed to switch off quickly, reducing the risk of electric shock.

The CB221-20 is an essential component for a wide variety of applications, providing reliable and effective protection against overcurrent and short-circuit conditions. It is a robust, reliable and simple to install device that requires very little maintenance, making it a great choice for both residential and commercial applications.
