CHB3090 - 90Amp Circuit Breaker Description
CHB3090 - 90 Amp Circuit Breaker
The CHB3090 is a 3-pole, 90-amp bolt-on circuit breaker built for use in panels that accept the CHB frame type. It carries a 10kA interrupting rating at 240VAC, making it suitable for protecting three-phase circuits in commercial and light industrial environments. Designed as a form, fit, and function replacement, this breaker matches the original specifications required for compatible CHB panelboards. With its bolt-on mounting style, the CHB3090 attaches directly to the panel bus for a secure connection. The 3-pole configuration supports three-phase power distribution, while the 90-amp rating helps protect conductors and connected equipment from overloads and short circuits. When maintaining existing electrical systems, matching the correct frame type, amperage, and interrupting capacity is critical—and this model is built to meet those requirements. Constructed with durable internal components, it is made to last when installed and used as intended.
