Siemens HFD63B200L - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

When you need dependable branch circuit protection in panelboards and load centers, the Siemens HFD63B200L delivers robust, precise performance. This 3-pole bolt-on molded case circuit breaker is rated at 200 A and 600 V, engineered to guard against overcurrent and short-circuit events with lasting reliability.

• Bolt-on mounting: a secure, vibration-resistant bus connection that stays aligned under normal operation and in demanding environments, reducing connection wear and intermittent faults.
• Thermal-magnetic trip unit: combines thermal overload protection with a fast magnetic response to short circuits, providing stable protection across varying temperatures and load conditions.
• Three-pole design ideal for 3-phase circuits common in commercial and light industrial settings, while still suitable for complex residential installations that require multi-phase protection.
• OEM-compatible with matching Siemens OEM load centers and panelboards for straightforward replacements and dependable system fit.
• Versatile application suited for residential, commercial, and light industrial installations, addressing a broad range of protection needs in a single breaker family.

What sets the HFD63B200L apart

This bolt-on breaker provides a rigid, reliable connection in panels where vibration, panel movement, or transport stresses are a concern. The integrated thermal-magnetic trip unit ensures repeatable protection performance, so you get consistent response to faults—minimizing damage to downstream equipment and reducing downtime in critical systems.
