Schneider Electric FH16020A I-Line Circuit Breaker

Schneider Electric FH16020A is a 1-pole, 20-amp I-Line molded‑case circuit breaker from the FH family. It is rated for 277 VAC and 125 VDC, delivering thermal‑magnetic overcurrent protection with an 80% continuous duty rating and a 65 kAIC interrupting capacity, designed for typical panel conditions. The unit uses a line-side I‑Line connection, a Phase A configuration, and load-side lugs, and it carries UL Listed and CSA Certified markings for use in compatible I‑Line panelboards and switchboards. This 1P 20A FH model targets 277V branch circuits such as lighting and general-purpose loads in commercial environments, and it fits the standard FH‑frame footprint for plug‑on mounting in Schneider Electric I‑Line systems. It provides both long‑time and instantaneous trip functions (thermal magnetic) in a compact form factor optimized for space in distribution panels. Ensure your panelboard supports FH‑series I‑Line breakers and the stated voltage ratings before installation. The FH16020A is a dependable choice when you need dedicated protection for a 20A, 277V circuit within an I‑Line distribution scheme.
