Siemens HFXD63B110N Molded Case Circuit Breaker

Siemens HFXD63B110N is a three-pole Sentron molded‑case circuit breaker engineered to protect three‑phase feeders and motors in commercial and industrial power systems. It carries a 110 A rating and is suitable for up to 600 V AC (and 500 V DC) circuits, using a thermal‑magnetic trip to provide precise overcurrent protection. The device offers a short‑circuit interrupt rating of 25 kA at 600 V, enabling safe interruption of fault currents in typical distribution panels and switchgear. As part of the HFXD family, this MCCB combines a compact frame with robust trip performance for use in Siemens‑compatible enclosures and assemblies, making it a common choice for protecting feeders and motor circuits in controlled industrial environments.
