ABB, SACE Tmax XT, XT2N Molded Case Circuit Breaker 3-Pole 100A, Breaking Capacity 10 kA, Fixed

This moulded case circuit-breaker provides overcurrent protection for three-phase electrical systems in industrial environments. It is designed for fixed installation with bolt-style connections and delivers Rapid interruption of fault currents using an instantaneous trip element suited to applications requiring prompt disconnection. The device is compatible with both AC and DC supply arrangements and is built to meet international IEC standards.

• 100 A rating delivers consistent conductor protection and load control
• 3‑pole configuration ensures simultaneous phase interruption for safety
• 10 kA breaking capacity limits prospective fault energy exposure
• Instantaneous trip offers immediate response to severe short circuits
• Rated for 690V AC operation for high-voltage distribution uses
• Bolt terminals provide secure, low-resistance connections

• Suitable for protection of industrial motor feeders and drives
• Ideal for switchboard sections in manufacturing facilities
• Used with DC control circuits up to 500V for battery-based systems
• Can be used for distribution protection in automation panels

It is intended for fixed mounting, requiring a secure panel or chassis location and appropriate mechanical fastening to support the breaker body during operation.

The device uses bolt-type terminals that necessitate torque-controlled fastening for reliable electrical contact and to prevent loosening under vibration.

It is rated to interrupt DC currents up to the specified voltage, providing separation capability for DC circuits at the declared maximum, though DC arcing characteristics differ from AC and require correct application.

The construction and performance adhere to IEC requirements, ensuring standardised test criteria for current interruption and endurance.
