FB2070 - 70Amp Circuit Breaker

FB2070 - 70Amp Circuit Breaker

Finding the right replacement breaker is about more than matching the amperage. The FB2070 is a 70 Amp, 2-pole FB thermal-magnetic circuit breaker built as a form, fit, and functional replacement for compatible electrical distribution systems. If you're maintaining an existing panel, replacing a failed breaker, or performing routine service, this unit provides the ratings and physical configuration needed to help keep compatible equipment operating as intended. Its compact footprint and included load terminals make installation straightforward when replacing an existing FB-series breaker with matching specifications.
