Key Features & Benefits

Superior Breaking Performance: With 50kA short-circuit breaking capacity, this MCCB provides reliable protection against severe fault conditions in industrial power distribution networks, manufacturing facilities, and commercial installations.

TMD Magnetic Release Technology: The non-adjustable magnetic-only trip unit ensures instantaneous protection against short circuits while maintaining simplicity and reliability without thermal overload protection—ideal for motor protection circuits and feeder applications where external overload devices are employed.

Robust Construction: Built with high-grade thermoplastic housing and silver-plated contacts, the TMAX XT2S withstands harsh industrial conditions including vibration, dust, and temperature fluctuations while maintaining consistent performance over its operational lifetime.

Space-Efficient Design: The compact footprint optimizes panel space utilization, allowing for higher circuit density in switchboards and distribution panels without compromising accessibility or safety clearances.

Application Scenarios

This circuit breaker excels in diverse industrial applications including motor control centers, transformer protection, generator switchgear, industrial machinery power distribution, HVAC systems, pump and compressor stations, and renewable energy installations. The 3-pole configuration makes it particularly suitable for three-phase power systems common in manufacturing plants, data centers, and commercial buildings.

Engineers frequently deploy the TMAX XT2S in coordination with thermal overload relays for comprehensive motor protection, in main distribution boards as feeder protection, and in sub-distribution panels where selective coordination with upstream protective devices is required.

Installation & Integration

The front-front terminal configuration facilitates straightforward wiring in tight enclosures, while the fixed mounting design ensures stable installation in vertical or horizontal orientations. Compatible with standard ABB accessories including auxiliary contacts, shunt releases, and undervoltage releases for enhanced functionality and remote monitoring capabilities.

Frequently Asked Questions

Q: What is the difference between TMD and TMA release types?
A: TMD features magnetic-only protection for instantaneous short-circuit tripping, while TMA includes both thermal overload and magnetic protection. The TMD variant is ideal when external overload protection is provided separately.

Q: Can this breaker be used in single-phase applications?
A: While physically possible, this 3-pole unit is optimized for three-phase systems. For single-phase applications, consider ABB's single-pole or two-pole TMAX XT variants for better cost-efficiency.

Q: What is the electrical life expectancy?
A: Under normal operating conditions at rated current, the TMAX XT2S provides 10,000+ mechanical operations and maintains reliable performance for 15-20 years with proper maintenance.

Q: Is this breaker suitable for DC applications?
A: This model is designed specifically for AC applications. For DC circuit protection, consult ABB's DC-rated circuit breaker portfolio with appropriate voltage and current ratings.
