R21-1-15.0A-B06CH-V

Circuit breakers are used in electrical circuits to control overcurrent, prevent short-circuits and protect circuits, machines, and personnel from damage and injury. The R21-1-15.0A-B06CH-V circuit breaker is a low voltage device that is designed to open and close the circuit when an overload, short-circuit, or ground fault occurs. It is used in residential, commercial, industrial, and other applications for protection of an electrical power system.

Application Field

The R21-1-15.0A-B06CH-V circuit breaker is designed specifically for low voltage applications, and is most often used in homes and small businesses where the electrical supply is not very large. It is suitable for use as a main circuit breaker in 120/240 volt AC single-phase and three-phase, four-wire or two-wire systems. It can also be used as a control circuit breaker in any type of electrical system.

The R21-1-15.0A-B06CH-V circuit breaker is not suitable for use in three-phase, three-wire systems. In those systems, a higher voltage, more powerful circuit breaker such as a 3-pole or 4-pole breaker is recommended.

The R21-1-15.0A-B06CH-V circuit breaker is typically used for protection in 120/240 VAC systems, and is available in 1-15 amps. It features a recessed thermal-magnetic trip unit with a rating of 15 amps at 240 volts. It is rated for a maximum voltage of 300 volts and is used in industrial control and household circuits.

Working Principle

The R21-1-15.0A-B06CH-V circuit breaker is designed to automatically open or close a circuit in order to prevent the flow of an overcurrent. It relies on a thermal-magnetic trip unit that detects when the current in the circuit exceeds its rated capacity. When this happens, the trip unit causes the breaker to open, interrupting the flow of current and protecting the circuit from overload or short-circuit conditions.

The thermal-magnetic trip unit also has a second function: it monitors the temperature of the circuit. If it detects an increase in temperature, it will actuate the breaker to open, interrupting the flow of current and preventing the temperature from rising too much and damaging the circuit.

The R21-1-15.0A-B06CH-V circuit breaker offers several advantages over other types of circuit breakers. It has a low operating temperature, a high interrupting capacity, and a high tolerance for sustained overloads. It also has a high short-circuit interruption rating and a low level of nuisance tripping. And, it is designed to provide reliable, long-term protection.
