Circuit breakers are safety devices that are designed to protect an electrical system from a high current overload or short circuit. The R21-61-15.0A-B06CV circuit breaker is a one-pole, 15-amp thermal-magnetic breaker. It is mainly used in residential and commercial applications, such as air-conditioners and power tools.

The R21-61-15.0A-B06CV circuit breaker operates on the principle of thermal-magnetic action. The device uses both thermal and magnetic action to protect the circuit from excessive current. The thermal component is a bimetallic disc that is installed in the breaker housing. When the current passing through the breaker exceeds the rated value, the thermal component will heat up. This causes the disc to expand, which in turn trips the breaker and breaks the circuit.

The magnetic component of the breaker is an electromagnet. When the current passing through the breaker exceeds the rated value, the electromagnet becomes energized and pull the trip bar, which in turn de-energizes the breaker and breaks the circuit. This type of protection is more reliable and accurate than the thermal component, since it responds more quickly to a current overload.

The R21-61-15.0A-B06CV circuit breaker is designed to protect against phase loss, phase reversal, undersized neutral, and phase unbalance. It also has a selectable infinite resistance and a trip time delay setting. This enables the breaker to respond quickly to a current overload and protect the circuit from damage.

Installing the R21-61-15.0A-B06CV circuit breaker is relatively easy. It is designed to fit into a standard electric panel box and does not require any additional wiring. The breaker should also be tested after installation to ensure that it is working properly.

The R21-61-15.0A-B06CV circuit breaker is an important device that is used to protect an electrical system from a high current overload or short circuit. It is mainly used in residential and commercial applications and operates on the principle of thermal-magnetic action. It is also designed to protect against phase loss, phase reversal, undersized neutral, and phase unbalance. Installing this type of breaker is relatively easy and requires no additional wiring.
