ABB XT1SU3015AFD000XXX 15A 3P Molded Case Circuit Breaker – XT1 Series – Thermal Magnetic – 35kA @ 480V

The ABB XT1SU3015AFD000XXX is a 15A, 3-pole molded case circuit breaker from the SACE Tmax XT family, engineered for industrial and commercial power distribution. It delivers reliable overcurrent protection using a fixed thermal-magnetic (LI) trip unit for accurate long-time and instantaneous response. Designed for unit mount installation, this breaker integrates seamlessly into ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and SACE Tmax XT panelboards. It serves as a direct replacement for legacy T1N015TL breakers and includes load side lugs for streamlined wiring.
