Siemens RXD63S200 A - 2000 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens RXD63S200A is a high-capacity, bolt-on molded case circuit breaker designed to deliver dependable branch-circuit protection in serious-panel environments. With a 2000A rating at up to 600V and a robust 3-pole configuration, this unit is built to handle substantial current demands while ensuring reliable protection for both power delivery and equipment integrity in panelboards and load centers.

• Secure bolt-on mounting: delivers a rigid, vibration-resistant bus connection that stays tight under demanding loads, reducing the risk of loose connections and nuisance trips over time.
• Thermal-magnetic trip unit: combines time-tested thermal overload protection with magnetic short-circuit trip for fast, stable, repeatable protection performance across varying temperatures and loads.
• OEM-compatible design: engineered to be readily drop-in compatible with Siemens OEM load centers and panelboards, simplifying replacement, stocking, and service scheduling.
• High-current, versatile application: 2000A rating makes it suitable for main feeder protection in large residential or light commercial setups, and for reliable branch protection in mid-size industrial panels.
• Three-pole, 600V capability: provides balanced, coordinated protection across all phases in three-phase systems, with a durable molded-case construction designed for long service life in demanding environments.
