Schneider Electric HDM36100U31X Circuit Breaker

Schneider Electric’s Square D HDM36100U31X is a three‑pole molded‑case circuit breaker (MCCB) rated for 600 V and 100 A, designed to provide reliable overcurrent protection for three‑phase feeders in industrial and commercial panelboards. As a Square D device, it combines robust construction with a compact form to fit standard enclosures used in distribution applications, helping protect feeders, motors, transformers, and other three‑phase loads from short circuits and overloads. The HDM36100U31X is built for use in common electrical distribution setups that require dependable interruption at 600 V, with a 100 A continuous operating rating and three‑pole configuration to ensure coordinated protection across all phases. This model supports typical Square D mounting and connection practices, making it compatible with conventional panelboard and switchgear installations where clear, maintainable protection is essential. In practical terms, it serves as a crucial safety and reliability component in industrial power systems, delivering predictable, fast disconnection of three‑phase circuits to minimize equipment damage and downtime.
