FA36050 - 50 Amp Circuit Breaker

FA36050 - 50 Amp Circuit Breaker

When you need a compatible replacement for an existing FA Series breaker, the FA36050 offers the ratings and configuration required for many commercial and industrial electrical systems. This 50-amp, 3-pole thermal-magnetic molded-case circuit breaker is designed for use in compatible I-Line panelboards, making it a practical choice for maintaining existing equipment without changing the original panel layout.

Its thermal magnetic trip unit reacts to both prolonged overloads and sudden short circuits, helping protect conductors and connected equipment during normal operation. Built to last, it serves as a form, fit, and functional replacement for compatible installations where matching the original specifications is essential.
