ABB, SACE Tmax XT, XT3N Molded Case Circuit Breaker 3-Pole 100A, Breaking Capacity 3.75 kA, Fixed

This moulded case circuit-breaker is a three-pole device designed to protect electrical installations in industrial and commercial systems. It operates as a fixed-mounted protection unit for use on AC and DC networks, providing Rapid interruption of fault currents and integration into switchgear assemblies where a compact, bolt-terminated solution is required.

• 100 A rating offers consistent conductor protection and load management
• 690V AC capability supports high-voltage industrial supplies
• 500V DC rating enables use on DC control and drive circuits
• 3.75 kA breaking capacity limits fault energy and equipment stress
• Bolt-style terminals ensure secure mechanical and electrical connections
• Instantaneous trip characteristic provides Rapid fault isolation

• Suitable for protecting three-phase motor feeders in automation panels
• Ideal for use in industrial distribution boards with high-voltage loads
• Used for DC supply protection in traction or drive systems
• Can be used for retrofit replacements in existing MCCB installations

It is designed for a fixed mounting configuration and must be secured to a panel or enclosure capable of supporting its weight and Terminal clearances.

Its performance is specified to meet internationally recognised IEC test criteria for circuit-breaker function and interruption.

Conductors are fastened using bolt terminals that provide a clamped electrical connection suitable for lugs or cable ends.

It has been developed with an approach that facilitates disassembly to support end-of-life component separation and recycling.
