CFD63B090L - 90A Circuit Breaker

CFD63B090L - 90A Circuit Breaker

When your dependable circuit protection is needed in commercial or industrial electrical systems, the CFD63B090L 90 Amp 3-Pole Molded Case Circuit Breaker is designed to deliver the ratings and compatibility required for many power distribution applications. Built on the Sentron CFD6 frame, this breaker combines a 90-amp rating, fuseless current-limiting design, and a non-interchangeable trip unit in a compact package that fits a wide range of existing installations.

Whether you're maintaining a facility, replacing a failed breaker, or keeping legacy equipment operating as intended, the CFD63B090L provides the form, fit, and function needed for compatible systems. Its impressive interrupting capacity—up to 200kA at 240VAC and 480VAC—makes it suitable for applications where substantial fault-current protection is required. The breaker is also HACR rated, operates at 50/60Hz, and is designed for use in environments up to 40°C (104°F).

Because it includes both line-side and load-side terminals, installation can be more straightforward in compatible equipment. Built for long-term service in demanding electrical environments, the CFD63B090L remains a trusted choice for facilities that depend on reliable circuit protection and system continuity.
