QGA222251

Schneider Electric’s QGA222251 circuit breaker provides reliable protection in electrical systems with a line-rated current capacity of 225 amps. This device is configured with two poles, making it suitable for typical dual-pole applications while operating at a rated voltage of 240 V AC. It is capable of handling network frequencies of both 50 and 60 Hz, adaptively supporting various system requirements.

Designed with a breaking capacity of 65 kA, the breaker complies with breaking capacity code G, making it effective in interrupting fault conditions. The unit uses thermal magnetic trip technology, which ensures prompt disconnection of electrical circuits. Under high conditions, the circuit breaker features a magnetic tripping current rated at 2400 A, with a hold current of 1200 A. Continuous operation is rated at 80%, providing a solid performance under typical load conditions.

The QGA222251 is engineered to withstand high impulse voltages, with a rating of 8 kV, enhancing its resilience in fluctuating electrical environments. For installation, the unit mount lug format allows for straightforward attachment, ensuring stability. A necessary tightening torque of 247.8 lbf.in is required for secure mounting, maintaining integrity under operational stresses.
