Siemens CFD63B200L - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Experience dependable protection for demanding electrical systems with the Siemens CFD63B200L. This 200A, 600V, 3-pole bolt-on molded case circuit breaker is engineered to deliver consistent overcurrent and short-circuit protection in panelboards and load centers, making it a reliable choice for residential, commercial, and light industrial applications.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the risk of loose contacts that can compromise protection and downtime.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance across varying temperatures and loads, quickly clearing faults while minimizing nuisance trips.
• OEM-compatible design is built to pair with matching Siemens load centers and panelboards, ensuring dependable fit and seamless integration.
• 3-pole configuration suits three-phase circuits common in commercial equipment, motors, and other multi-wire systems, delivering balanced protection across all phases.
• 200A / 600V rating covers feeder and branch circuit protection for medium-to-large installations, providing robust control over electrical distribution.

Why this matters in real-world settings: a bolt-on MCCB like the CFD63B200L is ideal for installations where vibration, mechanical stresses, or dense panel layouts could loosen connections. The secure mounting and precise thermal-magnetic trip characteristics help keep systems online, prevent arc-flash risks due to poor connections, and simplify maintenance by maintaining predictable response under fault conditions.

Ideal use cases include main breaker replacements in service panels, feeder protection for commercial load centers, and motor or equipment circuits in light industrial environments. It’s well-suited for electricians and facilities managers who value reliable protection with straightforward compatibility and installation in Siemens-based electrical ecosystems.
