Schneider Electric FA26040BC I-Line Circuit Breaker

Schneider Electric's Square D FA26040BC I‑Line 2‑pole molded‑case circuit breaker is a 40 A protective device built for 600 V systems and designed for I‑Line plug‑in panelboard installations. As part of the FA family, it delivers thermal‑magnetic overcurrent protection with an interrupting capacity up to 18 kA at 600 V and is 80% rated for continuous loads, making it suitable for feeders and branch circuits in commercial and light industrial power distribution. The unit uses line‑side I‑Line connections with a BC phase configuration and load‑side lugs that accept aluminum or copper conductors from 14 AWG to 1/0 AWG, providing wiring flexibility in FA‑series installations. It is rated for 600 VAC and up to 250 VDC maximum, aligning with typical industrial control and distribution requirements, and is UL listed and CSA certified for North American use. This I‑Line MCCB is designed to mount in FA‑series panelboards, offering reliable disconnection under overload or short‑circuit conditions for feeders and lighting or motor circuits in commercial or light industrial environments.
