Schneider Electric FH36020 Molded Case Circuit Breaker

Schneider Electric's Square D FH36020 Molded Case Circuit Breaker is a 3-pole, 600 V AC protective device from the FH family, rated for 20 A to safeguard 3‑phase feeders. Configured for I-Line plug-in mounting with load-side lugs for 14-4 AWG aluminum or copper conductors, it uses a thermal-magnetic trip mechanism and is 80% rated for continuous loads. Interrupting capability varies by voltage: up to 18 kA at 600 VAC (25 kA at 480 VAC and 65 kA at 240 VAC), providing swift fault isolation across typical industrial power systems. Designed for use in electrical distribution panels and equipment protection applications where reliable, code-compliant overcurrent protection for 3‑phase 600 V circuits is required.
