The FA24050AB Square D 2P 50A 277V AB PH I Line is a reliable and high-performance circuit breaker designed for commercial and industrial applications. With dual pole operation and a sturdy construction, it provides optimal protection for your electrical systems. Perfect for hot tub installations or other demanding environments.
The 'AB' suffix indicates the breaker uses an A-base (standard FA-frame base) with a B-style bolt-on mounting. This determines how the breaker connects to the panelboard bus. It's important to match this exactly when replacing an existing unit — using a different suffix (e.g., AC or AD) may result in an incompatible fit even within the same FA frame series.
The FA24050AB can serve as the overcurrent protection device feeding a hot tub or spa installation, provided your wiring method, load calculations, and local code requirements (including CEC Section 68 in Canada) are met. However, a dedicated disconnect (within sight of the equipment) may also be required. We recommend confirming with your electrical inspector or engineer before installation.
