Siemens RXD63B200 - 2000 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens RXD63B200 is a high-capacity 3-pole bolt-on molded case circuit breaker engineered for demanding electrical protection in panelboards and load centers. With a robust 2000 A rating at up to 600 V, this unit delivers reliable branch circuit overcurrent and short-circuit protection where it matters most—whether you’re wiring a residential service upgrade, a commercial distribution panel, or a light industrial distribution system. Key benefits you’ll feel in real-world use

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection that stays put through motor starts, thermal cycling, and dense panel layouts.
• Thermal-magnetic trip unit provides stable, repeatable protection—responding quickly to overloads and short circuits while minimizing nuisance trips during normal load transients.
• Three-pole configuration delivers comprehensive three-phase protection, essential for balanced motor loads and modern electrical systems.
• High-current capability at 2000 A with a 600 V maximum rating, designed for large distribution schemes in commercial and light industrial environments.
• OEM-load center compatibility—specifically designed to pair with matching Siemens OEM load centers and panelboards for a cohesive, dependable protection solution.
• Molded case design blends compact form with rugged performance, simplifying integration into standard enclosures and replacement schedules.

Why this matters for your project

If you’re upgrading an existing panel or building out a distribution network that demands serious current handling, the RXD63B200 provides a clear advantage. Its bolt-on mounting ensures a secure, vibration-resistant connection in environments where panel density and equipment vibration can challenge lesser breakers. The combination of a thermal-magnetic trip and a 3-pole configuration gives you precise, dependable protection across large feeders and multi-speed motor circuits, reducing downtime and extending panel life.
