Siemens JXD63B200 - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Siemens JXD63B200, a purpose-built 200A, 600V, 3-pole bolt-on molded case circuit breaker designed to protect your panelboards and load centers with confidence. Built to endure the rigors of busy electrical enclosures, this breaker delivers dependable branch-circuit overcurrent and short-circuit protection while maintaining solid, long-lasting connections in demanding environments.

• Bolt-on mounting for a rigid, vibration-resistant bus connection that stays secure through equipment movement and maintenance.
• Thermal-magnetic trip unit provides immediate, predictable protection: thermal for overloads and magnetic for short circuits, delivering stable, repeatable protection performance.
• 3-pole design tailored for three-phase circuits, compatible with matching Siemens OEM load centers and panelboards for seamless installation and replacement.
• Versatile across residential, commercial, and light industrial applications where reliable 200A protection is essential for distribution panels and motor-driven equipment.
• Part of Siemens’ molded case breaker family (model JXD63B200), engineered to align with Siemens protection schemes and installation practices for cohesive system performance.
