ABB XT1SU3090AFD000XXX 90A 3P Molded Case Circuit Breaker – XT1 Series – Thermal Magnetic – 35kA @ 480V

The ABB XT1SU3090AFD000XXX is a 90A, 3-pole molded case circuit breaker from the SACE Tmax XT1 family, designed for commercial and industrial power distribution systems. It provides reliable overcurrent protection using a fixed thermal-magnetic (LI) trip unit, ensuring consistent long-time and instantaneous response under fault conditions.

This unit-mount breaker installs directly into ABB SACE Tmax XT panelboards and switchboards and serves as a replacement for legacy T1S090TW models. With a 35kA interrupting capacity at 480VAC, it delivers strong fault-clearing performance for demanding electrical environments.
