Tmax XT Molded Case Circuit Breaker

The ABB SACE Tmax XT is a molded case circuit breaker (MCCB) designed for medium and low voltage power distribution and equipment protection. It features a frame size of 160–1600A and a breaking capacity of 18–200kA. It offers thermal-magnetic/electronic tripping, multiple installation options, and intelligent communication, making it suitable for power distribution, motor, and generator applications. It combines high current limiting, high reliability, and easy integration.

PRODUCT DETAIL

Core Structure and Protection Principle:

 

Dual Tripping System: Thermomagnetic tripping (overload inverse time + short-circuit instantaneous) or electronic tripping (long delay L / short delay S / instantaneous I / ground fault G, finely adjustable), current-limiting design, rapid disconnection to limit fault energy.

 

Key Design Features: Double insulation, forced operation and isolation performance; no derating for horizontal/vertical/horizontal mounting; built-in Bluetooth and Ekip Connect software, supporting remote commissioning and monitoring.

 

Application Scenarios:

 

Power Distribution Systems: Main switch and branch protection, improving selectivity and power supply continuity.

 

Motor Protection: Direct start/star-delta/soft start circuits, adaptable to heavy loads and frequent start-stop cycles.

 

Generators/Renewable Energy: Parallel and islanded operation protection, supporting neutral line enhanced protection.

 

Industry and Infrastructure: Data centers, medical facilities, chemical plants, and other scenarios with high reliability and monitorability requirements.
