Schneider Electric FA36015 I-Line Circuit Breaker

FA36015 is a Schneider Electric Square D molded‑case circuit breaker in the FA family, designed for I‑Line panelboards with a plug‑on style connection. This 3‑pole device provides 15 A of current rating for 600 VAC (and 250 VDC) systems, and it uses a thermal‑magnetic trip to protect three‑phase circuits from overcurrent. It features an I‑Line line‑side connection and load‑side lugs compatible with 14‑4 AWG aluminum or copper conductors, and it carries an 80% continuous rating for appropriate conductor temperatures. The interrupting capabilities are typically listed as 14 kA at 600 V, with higher ratings available at lower voltages (e.g., about 18 kA at 480 V and 25 kA at 240 V), making it suitable for protecting motors, transformers, and other three‑phase loads within commercial or light industrial distribution panels. This FA‑series breaker is a compact, modular solution intended to integrate with Square D I‑Line systems, providing reliable overcurrent protection in spaces where standard FA units are deployed. As a three‑pole unit, it is specifically suited for 3‑phase circuits in panelboard assemblies and equipment enclosures, delivering precise, field‑proven protection for medium‑voltage distribution and control applications.
