Schneider Electric FAP-16020 Circuit Breakers

Schneider Electric's Square D FAP16020 (FAP-16020) is a 1-pole molded‑case circuit breaker rated for 20 A on 277 V AC circuits. It belongs to the FAP family of Square D molded‑case breakers and is intended for overcurrent protection of 277 V loads typically found in commercial distribution, such as lighting circuits and other line‑to‑neutral circuits. The device offers an 18 kA short‑circuit rating at 277 V, enabling rapid interruption of fault currents in typical North American distribution systems. With a single pole and 20 A rating, the FAP16020 fits into Square D panelboards and switchgear that accept FAP breakers and protects branch circuits from overloads. The 18 kAIC rating helps engineers coordinate with upstream protective devices and conductor sizing for 277 V lighting and related loads. This model is commonly chosen when dependable protection is required without exceeding circuit conductor ratings in 277 V installations.
