Schneider Electric FH16020C I-Line Circuit Breaker

Schneider Electric FH16020C is a 1-pole, 20A I-Line molded‑case circuit breaker designed for 277V AC circuits in Schneider Electric's I‑Line panelboard systems. This Square D/Schneider device belongs to the Type FH family and uses a thermal‑magnetic trip mechanism to provide both long‑time and instantaneous overcurrent protection for a single‑phase load. The FH16020C is a plug‑in I‑Line protector, compatible with I‑Line panelboards that accept FH‑series breakers, and it follows the standard FH frame and installation geometry for reliable fit and predictable performance in commercial electrical distributions. It is specified for 277VAC operation, enabling safe control of loads in environments where 277V is used. Constructed as a molded‑case circuit breaker, the FH16020C combines compact form with robust protection features, and its 1P, 20A rating matches common branch‑circuit protection needs in 1‑phase distribution systems.
