Schneider Electric FA36015 Molded Case Circuit Breaker

Schneider Electric FA36015 is a 3-pole molded-case circuit breaker in the FA family, rated 15 A for 600 V AC (and 250 V DC) applications, designed for I-Line panelboard installations in Square D/Schneider Electric systems. It uses a line-side I-Line connection with ABC phase terminals and load-side lug connections that accept 14-4 AWG aluminum or copper conductors, and it employs a thermal-magnetic trip mechanism with an 80% continuous-load rating. This MCCB provides overcurrent protection for three-phase circuits in commercial and light industrial distributions configured for FA/I-Line panel buses, with an interrupting capacity listed as 14 kA at 600 VAC. As a legacy part still referenced in current Schneider Electric documentation and compatible with FA-series I-Line configurations, FA36015 serves as a direct 3P, 600 V, 15 A replacement option within its era of product lines, often used in existing FA panelboards where a precise 600 V, 15 A protection device is required. The FA36015’s combination of line-side I-Line connection, phase ABC wiring, and load-side lug terminals designed for 14-4 AWG Al/Cu keeps wire termination straightforward for installers maintaining older Square D installations.
