Siemens FXD62B200L - 200 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Siemens FXD62B200L is a robust 2-pole bolt-on molded case circuit breaker engineered for reliable branch circuit protection in panelboards and load centers. At 200A and 600V, it delivers dependable overcurrent and short-circuit protection where it matters most—in homes, commercial spaces, and light industrial settings.

• Secure bolt-on mounting creates a rigid, vibration-resistant bus connection that stays tight through equipment operation, reducing the risk of loose connections and heat buildup.
• Thermal-magnetic trip unitprovides stable, repeatable protection across varying loads and temperatures, minimizing nuisance trips while safeguarding downstream wiring and devices.
• 2-pole design with a common trip protects both live conductors, enhancing safety and preventing dangerous backfeed conditions in multiwire circuits.
• OEM-compatible and designed to work with matching Siemens load centers and panelboards, simplifying integration and ensuring electrical system coherence.
• Versatile application suitable for residential, commercial, and light industrial environments where high-current protection is required.

Why this breaker stands out

Unlike generic overcurrent devices, the FXD62B200L is purpose-built for environments where a secure, durable connection matters. The bolt-on design delivers a consistently tight bus bar interface even in vibration-prone installations, while the thermal-magnetic trip mechanism delivers predictable protection behavior across load profiles. This combination translates to fewer interruptions, longer equipment life, and easier serviceability when you need to upgrade panels or swap in a higher-capacity unit.

Ideal use cases

• Main and subpanels in residential settings requiring robust 200A protection
• Commercial electrical rooms and small to medium equipment rooms with demanding load patterns
• Light industrial circuits where vibration resistance and secure mounting are priorities

Practical tips for installation and use

• Verify compatibility with your Siemens OEM load center or panelboard to ensure seamless integration and coordinated protection curves.
• When replacing an existing breaker, match the amperage, voltage rating, and pole count to maintain designed protective coordination.
• Handle with care during maintenance to preserve the integrity of the bolt-on connection and trip unit calibration.
• Use in conjunction with properly rated downstream conductors and devices to maintain overall system protection and reliability.
