ABB XT5 600A 3P Molded Case Circuit Breaker – XT5 Series – Thermal Magnetic (Adjustable TM) – 65kA @ 480V

Delivering robust power distribution capabilities, this 600A molded case circuit breaker is part of the ABB SACE Tmax XT5 family, built for demanding industrial and commercial applications. It provides a reliable upgrade path for legacy Spectra RMS SG600 and Tmax T5H breakers when used with the appropriate retrofit kits.

This unit-mount MCCB installs into ABB ReliaGear neXT panelboards, ReliaGear SB switchboards, and SACE Tmax XT enclosures. It features an adjustable thermal-magnetic trip unit, allowing customized long-time and instantaneous (LI) protection to match specific system requirements.

With a 65kA interrupting capacity at 480VAC and up to 150kA at 240VAC, this current-limiting breaker ensures strong fault-clearing performance. Front terminals are provided for secure connections, while lugs are not included to support flexible configuration options.
