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.

Highlights

  • 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

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.
