Circuit breakers are an important part of home and industrial electrical systems. They help to protect people and property from electric shocks, fires and other disasters by automatically cutting power when an overload or short circuit is detected. The R21-4-7.50A-B06IV-V is a type of circuit breaker, designed for use in industrial and commercial applications.

The R21-4-7.50A-B06IV-V is a thermal-magnetic circuit breaker, which operates by combining two separate and distinct technologies. The first is a thermal system, which works based on the temperature and current flow of the circuit. When the temperature or current flow exceeds the breaker’s preset limit, the breaker trips, isolating the circuit from power. This limits the potential for damage to the system or a potential electric shock.

The second system is a magnetic system. This operates based on the strength of the current. When the current increase is rapid or exceeds the preset limit, the breaker trips, shutting off the circuit. This helps to protect the system from damage, or from potential fires or electric shocks.

The R21-4-7.50A-B06IV-V circuit breaker is suitable for use on all types of contactors and starters, including motor starters. It is also suitable for use in heating and lighting circuits, and in emergency lighting. It can be used as a single circuit breaker or in multiple pole configurations.

Due to its thermal-magnetic design, the R21-4-7.50A-B06IV-V circuit breaker offers a number of advantages over other types of circuit breakers. The thermal system ensures that the breaker will trip if the current or temperature of the circuit exceeds the preset limit. This prevents damage to the system and potential electric shocks. The magnetic system also helps to protect the circuit from potential overloads, short circuits or other hazardous conditions.

The R21-4-7.50A-B06IV-V circuit breaker is easy to install and maintain, and it is designed to last for many years of service. It is simple to replace when needed, and its robust construction ensures that it provides reliable protection for your circuit. It is UL 489 and UL 1077 listed, making it suitable for general industrial, residential and commercial applications.

In summary, the R21-4-7.50A-B06IV-V circuit breaker is an excellent choice for industrial and commercial applications. It is a reliable, easy-to-install and easy-to-maintain option, and its thermal-magnetic design ensures excellent protection of your circuit and equipment. This makes it an ideal choice for those looking for a safe, reliable and affordable circuit breaker.
