Siemens HJXD63B225 - 225 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens HJXD63B225 — a rugged, three‑pole bolt‑on molded case circuit breaker designed to protect your panelboards and load centers from overcurrent and short circuits with dependable, repeatable performance. Built for serious electrical environments, this unit delivers authoritative protection for three‑phase systems in residential, commercial, and light industrial applications.

• Secure bolt‑on mounting ensures a rigid, vibration‑resistant bus connection. That means fewer loose connections, enhanced electrical continuity, and long‑term reliability in panels exposed to equipment vibration or frequent power cycling.
• Thermal‑magnetic trip unit provides stable, predictable protection by combining overload (thermal) and short‑circuit (magnetic) responses. Expect fast, precise tripping when faults occur, reducing damage to downstream equipment and wiring.
• OEM‑grade compatibility designed to integrate with matching Siemens OEM load centers and panelboards, streamlining replacements and upgrades without compatibility surprises.
• Versatile, three‑phase protection ideal for distributing power to motors, HVAC systems, and other three‑phase loads common in commercial and light industrial settings.
