Schneider Electric FH36100 I-Line Circuit Breaker

Schneider Electric FH36100 is a three-pole, 100-amp molded-case circuit breaker (MCCB) designed for 600-volt systems and I-Line panel installations. As part of the FH family, it's built for thermal-magnetic protection of 3-phase circuits, helping prevent overloads and short circuits in distribution panels. The device uses an I-Line connection, enabling a plug-in installation into compatible Square D/Schneider Electric panelboards for quick, secure mounting and easy service later. With a 100 A rating, it suits feeders and branch circuits that feed motors, transformers, compressors, and other heavy loads in commercial and industrial environments. The FH36100 supports three-phase, four-wire systems and is configured for use in I-Line configurations across multi-pole panels, contributing to organized protection with a compact footprint. While designed for general protection duties, it is especially appropriate where reliable, code-compliant overcurrent protection is required in 600 V distribution networks, including data centers, manufacturing floors, and large facilities. Built to Schneider Electric’s standards for durable construction and consistent trip performance, the FH36100 integrates with the broader Square D protective ecosystem and complements other FH and I-Line devices in same-voltage configurations.
