Abb xt3su3225aff000xxx Molded Case Breaker 225A 3P

Product Description

The ABB xt3su3225aff000xxx is a Tmax XT3 frame molded case circuit breaker rated for 225 amps across 3 poles. It uses thermal-magnetic trip technology to provide overload and short-circuit protection in commercial and industrial power distribution systems. The breaker is rated for 600Y/347 volts AC with a 22 kAIC interrupting capacity. It ships in a fixed mounting configuration with front flat terminals, making it suitable for panel installations where space and terminal access are defined by the enclosure layout. Licensed electricians perform the installation and commissioning of this device.

This breaker is intended for use in 3-phase commercial and industrial electrical distribution panels operating at 480 volts AC. The fixed-mount, front flat terminal design suits switchboard and panelboard applications where the breaker is mounted directly to the panel structure. The 225-amp continuous rating covers a range of load types including motor branch circuits, feeder protection, and service entrance applications in facilities requiring reliable overcurrent protection.

Compatibility

Designed as an OEM-style molded case circuit breaker for 3-phase commercial and industrial panelboard and switchboard assemblies rated at 480 volts AC.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel before removing or installing the breaker. Verify that bus bar ratings, terminal torque requirements, and enclosure clearances are confirmed per the panel manufacturer specifications before energizing. Do not modify the thermal-magnetic trip mechanism or bypass factory-set protection elements.
