FXD63B110 - 110Amp Circuit Breaker

FXD63B110 - 110Amp Circuit Breaker

The Siemens FXD63B110 is a 110 Amp, 3-pole molded case circuit breaker from the SENTRON FD family with a thermal-magnetic trip unit. Rated for 600VAC, it delivers an interrupting capacity of 22kAIC at 600 volts and 35kAIC at 480 volts. Those numbers aren't just part of the specification sheet—they tell you how much fault current the breaker is rated to interrupt under the conditions Siemens specifies.

Material Compliance and Certifications

The Siemens FXD63B110 complies with UL 489 and IEC 60947-2 standards for molded case circuit breakers and meets Siemens' published RoHS substance restrictions.

Installation should be completed by qualified electrical personnel in accordance with applicable electrical codes and manufacturer recommendations.

Where It Works Best

The FXD63B110 is commonly installed in switchboards, panelboards, feeder circuits, manufacturing facilities, warehouses, commercial buildings, and other industrial electrical distribution systems that use Siemens FD-frame breakers. It's a common choice when replacing a breaker with matching electrical ratings and the same frame style. Because Siemens supplies this model without lugs installed, the appropriate lug configuration can be selected to meet the requirements of the installation.
