ABB XT4 225A 3P Molded Case Circuit Breaker – XT4 Series – Thermal Magnetic (TMF) – 100kA @ 480V

Offering extra-high interrupting capacity, this 225A molded case circuit breaker is part of the ABB SACE Tmax XT4 family, engineered for demanding commercial and industrial power distribution systems. Designed as a direct replacement for legacy T4L225TW breakers, it enables seamless system upgrades without modification.

This unit-mount MCCB integrates into ABB ReliaGear neXT power panels, ReliaGear SB switchboards, and SACE Tmax XT panelboards. It features a fixed thermal-magnetic (TMF) trip unit that delivers dependable long-time and instantaneous (LI) protection against overloads and short circuits.

With a powerful interrupting capacity of up to 200kA at 240VAC and 100kA at 480VAC, this breaker ensures superior fault-clearing performance. The current-limiting design enhances system protection, while included load-side lugs and mounting hardware simplify installation.
