FAQs
BRHX290 uses plug-on mounting designed for BR series panelboards. It is a two-pole device rated for 90 A at 120/240 V with a 22 kAIC interrupt capacity. For best results, ensure compatible bus-stabs and mounting rails are clean and aligned, and verify there is no inadvertent de-rating due to enclosure density or ambient temperature.
BRHX290 provides a 22 kAIC interrupt rating with a fixed trip characteristic suited to non-interchangeable BR devices. It is rated for 90 A at 120/240 V and is designed for rapid disconnection on overload or short-circuit conditions, helping protect conductors, devices, and downstream equipment from damaging fault currents.
Yes. The two-pole configuration and 90 A rating at 120/240 V make BRHX290 suitable for motor feeders and control circuits in industrial panels. Its 22 kAIC protection helps manage fault currents common in motor starting and energization transients, while plug-on installation reduces commissioning time in motor control applications.
