Circuit breakers are electrical devices used to protect wiring systems and equipment from overload damage. Overcurrent protection can be provided by either conventional circuit breakers or fuses. The 4410.9021 circuit breaker is specifically designed to provide overcurrent protection in a variety of applications.

The 4410.9021 is a compact circuit breaker with an interrupt rating of 18kA at 480V. This 3-pole breaker is UL listed and rated for UL/CSA 489-5. It is suitable for use as an overcurrent protective device for branch circuits, control circuits, and lighting circuits in industrial, commercial, and residential installations.

A unique feature of the 4410.9021 circuit breaker is its low-speed operating mechanism. This feature allows the circuit breaker to be used in power conversion processes, including those with large voltage swings, where a higher-speed breaker could not operate reliably. As the trip current gradually increases, the mechanism of the circuit breaker allows it to open faster than a conventional breaker, reducing the risk of damage to the system.

The 4410.9021 circuit breaker also has adjustable overcurrent settings. The adjustable settings can be adjusted to provide different levels of protection for different types of equipment. This allows the circuit breaker to be used for protecting specific pieces of equipment on a circuit, rather than providing a blanket level of protection for the entire circuit.

In addition to providing overcurrent protection, the 4410.9021 circuit breaker also has a trip indicator. The indicator is used to notify the user of any tripped circuits. This helps to reduce the risk of exposed wires or other hazardous conditions. The trip indicator may also be used to identify problems with the circuit, allowing the user to quickly identify and isolate the issue.

The 4410.9021 circuit breaker is designed to provide high-performance overcurrent protection in a variety of applications. It is suitable for use in commercial, industrial, and residential settings. The adjustable settings allow it to be used to protect specific pieces of equipment instead of providing a blanket level of protection for the entire circuit. The trip indicator helps to reduce the risk of exposed wires or other dangerous conditions, and helps to quickly identify and isolate problems with the circuit. The low-speed operating mechanism of the 4410.9021 allows it to be used for power conversion processes, making it a versatile circuit breaker for a variety of applications.
