Buy Direct Square D KI36110 – 110A 3 Pole Molded Case Circuit Breaker

Part of the legacy K-Frame series, this 110A, 3-pole MCCB delivers robust thermal-magnetic protection for industrial environments. Designed for Square D I-Line panelboards, it features a plug-on mounting style for quick installation. It serves as a replacement for older setups and is superseded by the HRA36110. With a 200kAIC rating at 480VAC, its current-limiting design reduces let-through energy, minimizing damage to downstream components during short circuits.
