ABB, Tmax XT, Tmax XT Molded Case Circuit Breaker 4-Pole 63A, Breaking Capacity 65 kA, Fixed

This moulded case circuit-breaker provides overcurrent protection and manual reset capability for low-voltage industrial installations. Designed for fixed mounting and four-pole configurations, it is suitable for protecting distribution circuits and electrical equipment where coordinated thermal and magnetic tripping is required. The unit operates across AC and DC systems and meets recognised European and international standards.

• 63 A rating offers consistent overload protection for distribution circuits
• Thermal-magnetic trip delivers combined overload and short-circuit response
• 65 kA interrupting capacity protects against high fault currents
• Fixed terminals allow secure, vibration-resistant connections
• Lever-reset actuator enables quick manual reclosure after fault clearance
• Rated for 500V DC and 690V AC operation for versatile system compatibility

• Suitable for motor-feeder protection in automation panels
• Ideal for distribution board protection in industrial facilities
• Used with DC-supply equipment requiring high-voltage interruption
• Can be used for four-pole isolation in three-phase-plus-neutral systems
• Suitable for retrofit of control cubicles needing high interrupting capacity

The device is designed for fixed mounting to panel or enclosure backplates, ensuring a stationary installation without removable Terminal adaptors.

The thermal element responds to prolonged overloads while the magnetic element trips instantaneously on high-magnitude short circuits, enabling selective response based on fault characteristics.

Compliance with CE, IEC and RoHS indicates adherence to relevant safety and material standards for deployment in regulated environments.

The breaker presents a Compact footprint with a narrow width and reduced depth and height to assist dense component placement without sacrificing interrupting capability.
