The QBA222002 model from Schneider Electric is a robust circuit breaker suitable for critical electrical systems. It is rated for a current of 200 Amperes and operates effectively at a voltage of 240 Volts AC. This unit supports both 50 Hz and 60 Hz power supply frequencies, making it versatile for different applications.
With a dual pole configuration, this circuit breaker employs thermal-magnetic trip technology, ensuring precise and reliable operation. The magnetic tripping current can reach as high as 2400 A, while the magnetic hold current is rated at 1200 A. This ensures that the breaker provides adequate protection against overcurrent scenarios while maintaining operational continuity.
Designed with a breaking capacity of 10 kA for 240 V AC, the QBA222002 is prepared to handle fault conditions efficiently. This circuit breaker also boasts impressive mechanical durability, rated for 1000 cycles under loaded conditions and 5000 cycles when unloaded. It can also be easily mounted using an I-Line bracket, making installation straightforward. Electrical connections are made simple with both I-Line connections for the line side and lugs for the load side.
In terms of dimensions, the QBA222002 measures 164.34 mm in width, 76.2 mm in height, and 99.82 mm in depth. To ensure secure cable connections, it requires a tightening torque of 247.8 lbf.in (28 N.m) for wire sizes ranging from 25 to 150 mm² (AWG 4 to 300 kcmil).
This circuit breaker meets various environmental standards, including UL, CSA, and NEMA, ensuring its reliability and safety in diverse operational environments.
