Siemens HFXD63B250L - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Siemens HFXD63B250L is a purpose-built 3-pole molded case circuit breaker designed to deliver reliable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. At 250 A and 600 V, this unit is ready to support demanding residential, commercial, and light-industrial applications with confidence.

Why this breaker stands out

• Compact molded-case design maximizes panel space and simplifies installation, helping you fit more protection in tight electrical enclosures without compromising performance.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining thermal sensing for overload with magnetic trip for instantaneous response to short circuits. This means predictable protection and fast isolation when incidents occur.
• Three-pole configuration is ideal for three-phase systems, ensuring balanced protection across all conductors in commercial and light-industrial setups.
• OEM-ready compatibility engineered to pair with matching Siemens load centers and panelboards, simplifying selection, labeling, and long-term maintenance.
• High-current, high-voltage capability rated for 250 A and up to 600 V, giving you the headroom to protect sizable branch circuits while meeting code-driven requirements.

Real-world use cases

• Upgrading service panels in small offices or retail spaces that run multiple three-phase circuits, ensuring consistent protection across all legs.
• Installing new load centers in light industrial facilities where compact protection devices save space and reduce cabinet clutter.
• Replacing aging breakers in existing Siemens panelboards to restore reliable overcurrent protection and maintain system integrity.

What problems it solves

• Prevents damage from overcurrent and short circuits by rapidly interrupting faulty circuits, preserving equipment and reducing downtime.
• Streamlines panel design with a compact footprint, giving technicians more room for wiring and future expansion.
• Eliminates compatibility concerns by aligning with Siemens’ own OEM panel products for straightforward integration and serviceability.
