R21-62-20.0A-B06CV-V Circuit Breaker

A R21-62-20.0A-B06CV-V Circuit Breaker is a mechanical switch designed to protect electrical circuits against overload. A circuit breaker is like a fuse, in that it operates when an overload current and/or short circuit current exceeds the rating of the circuit breaker and closes the contacts to disrupt the circuit. Circuit breakers are designed to be reset when repaired or replaced and are often used in commercial and industrial installations where an excessive current can lead to an electrical hazard, such as fire or shock.

The R21-62-20.0A-B06CV-V circuit breaker is typically used in AC systems up to 600 volts. It has a voltage rating of 20.0A and is mounted in a 1/2 inch frame size. The operating temperature range for this circuit breaker is -30°C to 70°C. This breaker has a thermal magnetic trip current rating of 12,000A and is rated for up to 15,000A at its strong trip points.

The R21-62-20.0A-B06CV-V circuit breaker is commonly used in applications that require protection against over current protection, short-circuit protection, undervoltage protection, and protection against mis-wiring. This type of circuit breaker can be used to protect circuit breaker panels, distribution boxes, generator sets, switch boards and many other applications.

Working Principle

The R21-62-20.0A-B06CV-V circuit breaker works on the principle of thermal-magnetic trip action. When an overload or short circuit current occurs in the circuit, the temperature of the component increases. This thermal detection is done by a bimetallic element that is part of the structure. The increased temperature causes the bimetallic component to move and open the contacts, thus breaking the circuit and preventing further damage.

In addition to the thermal trip protection, the R21-62-20.0A-B06CV-V circuit breaker is also equipped with a magnetic trip which is triggered when a greatly increased level of current passes through the breaker. This trip action is used as an override feature to ensure the safety of the circuit breaker. When a fault occurs, the magnetic trip opens the contacts and keeps the circuit from being re-energized until the fault is cleared.

The R21-62-20.0A-B06CV-V circuit breaker is a reliable and cost-effective solution for protecting electrical circuits. This type of breaker is suitable for many types of applications and provides an extra layer of protection against overheating and short-circuits. With its thermal-magnetic trip action, the R21-62-20.0A-B06CV-V circuit breaker is an ideal solution for protecting electrical circuits in industrial and commercial installations.
