Schneider Electric FA36020 Molded Case Circuit Breaker

FA36020 is a 600 V AC molded-case circuit breaker from Schneider Electric’s FA family (Square D legacy), rated for 20 A in a 3-pole configuration that provides three-phase protection for distribution panels, with a maximum operating voltage of 600 VAC and a DC rating up to 250 VDC. It employs a thermal-magnetic trip mechanism that combines thermal overload protection with magnetic short-circuit interruption, designed for reliable protection in demanding environments, and it is intended for installation in Schneider Electric compatible panels using I-Line mounting, with line-side and load-side terminations suitable for secure connections to aluminum or copper conductors. The FA36020 carries an interrupting rating up to 14 kA at 600 V, a specification that supports protection against high fault currents in typical industrial or commercial power-distribution schemes, while the molded-case construction provides rugged durability and standardized mounting geometry to simplify panel layout and cross-reference with other FA-series devices. As part of the FA family, this unit is designed to integrate with other FA-series breakers to deliver coordinated protection across a panel and is commonly used as a main or feeder breaker in three-phase mains, machine mains, and distribution sections where dependable, code-compliant circuit protection is required.
