Siemens FXD63B200L - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens FXD63B200L — a robust 200 A, 600 V, three-pole bolt-on molded case circuit breaker designed to protect your electrical distribution with precision. Built for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters, this unit is engineered to keep critical systems running smoothly in residential, commercial, and light industrial environments.

Why the FXD63B200L stands out

• Secure bolt-on mounting — creates a rigid, vibration-resistant bus connection that stays solid over time, reducing the risk of loose connections in demanding installations.
• Thermal-magnetic trip unit — delivers stable, repeatable protection by responding to overloads and short circuits with predictable tripping behavior.
• Three-pole design (3P) — ideal for three-phase circuits, enabling balanced protection across a 3-phase distribution system.
• OEM-compatible — designed to be compatible with matching Siemens OEM loadcenters and panelboards, simplifying replacement and service.
• High-capacity protection — 200 A rating provides reliable protection for feeder and branch circuits in larger panels, while supporting safe expansion of electrical infrastructure.

Ideal applications and practical use

• Service panels and subpanels where durable, long-life protection is essential in residential and commercial settings.
• Commercial spaces with three-phase distribution requiring robust overcurrent and short-circuit protection.
• Light industrial environments where vibration resistance and secure mounting are priorities to prevent nuisance trips and connection issues.
• Replacement or upgrade in Siemens-compatible panelboards and loadcenters to maintain system continuity and compatibility.
