QBA222004

In the Schneider Electric QB Series, the QBA222004 circuit breaker stands out with its efficient design. This device is specifically rated for a voltage of 240 VAC and is well-suited for 1-phase applications with 2 poles. It supports a rated current of 200 A, making it capable of managing significant electrical loads.

The circuit breaker integrates a thermal magnetic protection scheme that combines the benefits of both long-time and instantaneous functions. This allows for robust circuit protection and quick response to fault conditions, with an interrupt rating of 10 kA, ensuring it can handle brief fault conditions without damage.

Installation is simplified with a 1-line style plug-in connection. The breaker itself weighs approximately 2.173 kg, which contributes to its sturdy build without being overly cumbersome. It is engineered to perform within a temperature range, operating effectively from 0°C to 40°C while also capable of withstanding conditions that reach up to 1000 meters above sea level. The design also accommodates a maximum relative humidity of 80% (non-condensing), ensuring that it remains functional even in varying environmental conditions.
