Circuit breakers are critical safety components found in virtually every commercial, industrial, and residential building around the world. They are designed to protect and control electrical systems from overloading and short-circuiting. These essential devices ensure the safe and reliable operation of electrical systems in a variety of applications. The R21-2-20.0A-B108CV-V is a circuit breaker that is designed for industrial and commercial applications and provides a reliable form of protection and control.

The R21-2-20.0A-B108CV-V circuit breaker is a double pole breaker that is rated at 20A, 125/250/480VAC, 50/60Hz. It is UL and cUL Listed, and is suitable for both panel and din rail mounting. The compact design of this breaker allows it to fit in a wide variety of spaces and accommodate a wide range of applications. It features a manual trip lever, a removable terminal cover, and an adjustable trip setting.

The primary purpose of the R21-2-20.0A-B108CV-V circuit breaker is to protect against short circuits by constantly monitoring the current flow in the electrical circuit. The breaker utilizes a thermal-magnetic trip unit, which consists of two distinct parts. The first part is a thermal element, which senses the heat generated in the conductor due to the excessive current flow. The second part is a magnetic element, which senses the magnetic field generated from the current. When the combined force of these two elements reaches its predetermined level, the breaker will trip and disconnect the circuit.

The R21-2-20.0A-B108CV-V circuit breaker can be used in a variety of situations, such as in commercial and industrial buildings, power distribution stations, and motor control centers. It is also suitable for use in hazardous applications, due to its UL and cUL Listings. The adjustable trip setting allows the user to fine-tune the level of protection offered by the breaker and ensure that it is suitable for their application.

Overall, the R21-2-20.0A-B108CV-V circuit breaker is well-suited for industrial and commercial applications. Its adjustable trip setting provides the user with the flexibility to fine-tune the protection of the breaker to their specific application. The UL and cUL Listings of the device also make it suitable for a variety of hazardous applications. As a result, this is an ideal solution for those looking for reliable protection and control in their electrical systems.
