RXD63B200 - 2000Amp Circuit Breaker

RXD63B200 - 2000Amp Circuit Breaker

When you're maintaining an existing electrical distribution system, finding the right replacement circuit breaker comes down to matching the details that matter. The Siemens RXD63B200 is a 2000-amp, 3-pole molded case circuit breaker (MCCB) from the Siemens SENTRON family, designed for compatible equipment that requires an RD-frame breaker. With a maximum voltage rating of 600V AC, an interrupting capacity of 25kA at 600V AC, and 50kA at 480V AC, this breaker provides the specific electrical characteristics needed for approved applications in commercial and industrial power distribution systems.

Key Features and Benefits

• 2000-Amp Current Rating: Provides overcurrent protection for compatible electrical distribution systems designed to use a 2000A breaker.
• 3-Pole Configuration: Designed for approved three-phase electrical applications that require simultaneous protection of all three poles.
• Thermal-Magnetic Trip Mechanism: Combines thermal overload protection with magnetic short-circuit protection.
• Siemens RD-Frame Design: Features a defined frame size and construction for compatible equipment requiring this specific breaker configuration.
• Fixed, Non-Interchangeable Trip Unit: Preserves the manufacturer's designated trip-unit arrangement for matching replacement applications.
• Supplied Without Lugs: Requires separately verified, manufacturer-approved termination hardware appropriate for the installation.
