FB2090 - 90Amp Circuit Breaker

FB2090 - 90Amp Circuit Breaker

Finding the right replacement breaker means more than matching the amperage—it also requires the correct frame type, interrupting capacity, and physical dimensions. The FB2090 is a 90 Amp, 2-pole FB thermal-magnetic circuit breaker built as a form, fit, and functional replacement for compatible legacy electrical systems. Whether you're replacing a worn breaker during routine maintenance or restoring service after a failure, this unit helps maintain the original configuration of your existing equipment.

The FB2090 uses a thermal-magnetic trip mechanism to provide dependable protection against both overloads and short circuits.
