Abb XT4SQ3250AFF000XXX Circuit Breaker 250A 480V 3P

Product Description

The ABB XT4SQ3250AFF000XXX is a 3-pole molded case circuit breaker rated for 250 amps at 480 volts, built around a thermal-magnetic fixed (TMF) trip unit with an adjustable range of 250 to 2500. It is UL and CSA listed, making it suitable for commercial and industrial power distribution panels where code-compliant overcurrent protection is required. The fixed-front (F F) mounting configuration suits standard enclosure and panel installations. Licensed electricians typically specify and install this breaker in switchboards, panelboards, and motor control centers.

This breaker fits commercial and light industrial distribution applications where a 250A frame is required. The thermal-magnetic trip mechanism provides both overload and short-circuit protection in a single device. The 3-pole configuration is appropriate for 3-phase distribution systems operating at 480 volts. Its UL/CSA listing satisfies the approval requirements common to commercial construction and industrial facility projects across the US and Canada.

Key Features

• 250A continuous current rating at 480 volts AC
• 3-pole configuration for 3-phase distribution systems
• Thermal-magnetic fixed (TMF) trip unit with 250-2500 adjustment range
• Fixed-front (F F) mounting for standard enclosure installation
• UL and CSA listed for compliance on commercial and industrial projects

Compatibility

Designed as an OEM-style replacement or new-installation circuit breaker for commercial and industrial 3-phase panelboards and switchboards requiring a 250A 3-pole molded case breaker at 480 volts.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel or switchboard before mounting or wiring the breaker. Verify that conductor sizing, torque requirements, and enclosure ratings match the breaker specifications prior to energizing. Do not exceed the breaker's rated voltage or current when selecting for a circuit.
