Schneider Electric FHB36100 ILine Circuit Breaker

Schneider Electric Square D FHB36100 I-Line molded-case circuit breaker is a 100 A, 3-pole device rated for 600 V AC, designed for line-side I-Line connections in industrial power-distribution systems. It uses a thermal-magnetic trip mechanism and is rated for 80% continuous operation. Load-side terminals accept aluminum or copper conductors from 14 AWG to 1/0 AWG, and the unit follows an ABC phase arrangement (A–B–C). Short-circuit protection is up to 18 kA at 600 V, with higher ratings of 25 kA at 480 V and 65 kA at 240 V, depending on system voltage. This FH-series breaker is commonly used to protect feeders in Square D I-Line panelboards and similar installations within commercial and industrial electrical distribution.
