Circuit breakers play a paramount role in the safety of modern electrical systems. Through their precise and calculated reaction to electrical overload conditions, they protect both people and equipment from catastrophic damage due to excess current or electrical arcing.

One type of these critical components is the T21-1-2.00A-01-20AL-V, a current-limiting circuit breaker designed for general purpose use. This device offers a combination of sensitive protection and good current limiting performance in applications rated up to 600V, with a maximum continuous current rating of 2,000A.

Application Field

The T21-1-2.00A-01-20AL-V is primarily intended for use in the industrial sector. Specifically, it can be used in systems with maximum available fault currents up to 10 kA, bus transfers of up to 2,500A, and terminal voltage ratings of 600V or less. This device is suitable for applications such as control panels, switchboards, and other general support equipment.

Working Principle

The T21-1-2.00A-01-20AL-V operates by using a combination of magnetic and thermal principles. Once the device is energized and current begins to flow, the magnetic force generated synchronizes the movement of the device\'s trip mechanism and its electrodes. This process allows for the trip time of the device to remain within certain limits, setting it apart from other circuit breakers.

The breaker also has thermal elements that work as overload protection. When a large amount of current flows through, the device can detect it and open the circuit. During normal operation, the heat dissipating through these elements keeps the breaker in an open state, so that even if a short circuit occurs, current won\'t flow and a fault won\'t occur.

The trip time of the device is set in advance and can be adjusted according to the application. Adjusting the trip time allows the circuit breaker to react faster in the event of an overload, protecting the system from a potentially dangerous event.

The T21-1-2.00A-01-20AL-V is a highly configurable circuit breaker. It can be customized to meet specific application requirements, such as trip time and operational temperature range. By having this level of flexibility, users can maximize the performance of the device in their particular applications, leading to safer, more reliable operation.
