FA26040AB - 40 Amp Circuit Breaker

FA26040AB - 40 Amp Circuit Breaker

When you need a replacement breaker for an existing I-Line electrical distribution system, it's essential to match the original specifications. The FA26040AB is a 40 Amp, 2-pole FA molded case circuit breaker designed for compatible I-Line plug-in panelboards using an A-B phase configuration. Its thermal-magnetic trip mechanism protects against overloads and short circuits, making it a dependable choice for maintaining existing commercial and industrial electrical systems without altering the original equipment configuration.

Rated with an interrupting capacity of 25kA at 240VAC and 18kA at 480VAC, the FA26040AB is intended for 60Hz applications and is suitable for operation in ambient temperatures up to 40°C. This breaker is also HACR Type rated for compatible heating, ventilation, air conditioning, and refrigeration equipment.
