HHFXD63B225

The Siemens HHFXD63B225 is a molded case circuit breaker designed for robust power distribution protection. It is part of Siemens’ Sentron family of thermal‑magnetic circuit breakers built on an FD‑frame platform and intended for use in industrial and commercial electrical systems. The device is rated at  amps,  VAC, and features poles for three‑phase applications, providing reliable overcurrent protection where high fault currents may be encountered. Its thermal‑magnetic trip unit offers both long‑time (overload) and instantaneous (short‑circuit) protection ensuring quick response to abnormal current conditions. The breaker is configured for Bolt-On mounting and includes load‑side lugs, meeting UL 489 and IEC 60947‑2 performance standards with a high interrupting rating that can safely clear significant fault energies in the system.

Engineered for demanding environments, this molded case breaker delivers an extra‑high {aic rating} interrupting capacity suitable for systems where high fault currents are a concern, making it a strong choice for manufacturing plants, commercial switchgear, and critical infrastructure installations. Typically assembled with a standard 40 °C frame and a non‑interchangeable trip unit, it offers stable performance across a variety of load profiles and operational conditions. The robust construction and compliance with industry safety standards ensure long‑term reliability in protecting feeders, branch circuits, and electrical distribution equipment.
