SIEMENS FXD63B200 Molded Case Circuit Breaker 200A 3 Pole

SKU CH-D5Q0-R2359

Three-pole molded case breaker rated 200 A with 22 kA interrupting capacity at 600 V AC and 500 V DC

  • 200 A rating protects 600 V AC circuits up to 22 kA interrupting
  • Three-pole thermal-magnetic trip covers all phases with fixed 200 A setting
  • 250 A frame fits Sentron panelboards and SB switchboards without lugs
  • 500 V DC rating adds flexibility for mixed AC/DC installations
  • Free-standing mount simplifies panel layout and maintenance access

SIEMENS FXD63B200 200A Three-Pole Breaker

The SIEMENS FXD63B200 is a molded case circuit breaker rated 200 A with a 600 V AC and 500 V DC voltage rating. It uses a thermal-magnetic trip unit with fixed instantaneous settings and a 22 kA interrupting rating at 600 V AC. The three-pole device fits FXD6-A series frames and mounts free-standing in compatible panelboards.

Verify Panelboard Compatibility Before Ordering

Confirm the breaker will be installed in an SB switchboard or Sentron panelboard without lugs as specified. The unit requires a 250 A frame size and ABC phase connection. Ensure the existing bus arrangement accepts a standard thermal-magnetic breaker with terminal lug connections.

Thermal-Magnetic Trip

The thermal-magnetic mechanism provides overload and short-circuit protection without adjustable instantaneous settings. Heat dissipation follows the 200 A continuous rating within the 250 A frame. Operational noise is limited to mechanical contact movement during trip events. Power draw in normal use is the load current passing through the poles.

Questions about this item

Does the FXD63B200 breaker ship with lugs or must they be ordered separately?

The breaker includes a terminal connection lug as standard equipment, so no separate lug purchase is required for installation.

Should I choose the 200 A fixed-trip version or a model with adjustable trip settings?

This FXD6-A frame has both high and low amp trip settings fixed at 200 A; select it when the application demands a non-adjustable 200 A trip point.

What does the 22 kA AIR rating at 600 V AC mean for my panelboard?

The breaker can safely interrupt up to 22 000 amps of fault current at 600 V AC, making it suitable for SB switchboards and Sentron panelboards rated at or below that level.
