ABB TMAX XT 4-Pole MCCB - High-Performance 400V 50kA Circuit Protection
The ABB TMAX XT 4P MCCB (1SDA067559R1) delivers industrial-grade overcurrent protection with 50kA breaking capacity at 400V AC. Engineered with thermomagnetic trip technology and four-pole switching, this molded case circuit breaker safeguards critical electrical distribution systems against overloads, short circuits, and phase failures in demanding industrial environments.
Key Technical Parameters
- Catalog Number: 1SDA067559R1
- Pole Configuration: 4-pole (3P+N or 4P)
- Rated Voltage: 400V AC (Ue)
- Breaking Capacity: 50kA at 400V (Icu)
- Current Rating: XT2S 160 frame, TMA 125-1250A adjustable
- Trip Unit: Thermomagnetic release (TMA)
- Adjustment Range: 0.7-1.0x In (thermal), 5-10x In (magnetic)
- Terminal Type: Front fixed terminals
- Mounting: Fixed installation
- Operating Mechanism: Toggle operation with trip-free mechanism
- Electrical Life: 25,000 operations at rated current
- Standards Compliance: IEC 60947-2, UL 489
- Dimensions: 140 x 210 x 86mm (W x H x D)
Industrial Protection Applications
Designed for main distribution boards, motor control centers, and feeder protection in manufacturing plants, data centers, and commercial buildings. The 4-pole configuration provides simultaneous disconnection of all phases plus neutral, essential for IT power systems, generator installations, and applications requiring complete isolation. The 50kA short-circuit rating handles fault currents in high-power networks fed by transformers up to 1600kVA.
Installation & System Integration
Compatible with ABB's modular accessory ecosystem including shunt trips, undervoltage releases, auxiliary contacts, and motor operators for remote control integration. Front-accessible terminals simplify wiring in tight enclosures. The adjustable thermomagnetic trip unit allows fine-tuning protection curves to match downstream equipment characteristics, preventing nuisance tripping while maintaining selective coordination with upstream protection devices.
Common Technical Questions
Q: What's the difference between 3P+N and 4P configurations?
A: In 3P+N mode, the neutral pole switches but doesn't trip; in 4P mode, all four poles trip simultaneously. Configuration depends on system grounding and local electrical codes.
Q: Can the trip settings be adjusted in the field?
A: Yes, the TMA release features accessible adjustment dials for both thermal (overload) and magnetic (short-circuit) thresholds without requiring calibration tools.
Q: Is this breaker suitable for motor protection?
A: While capable of motor circuit protection, coordination with motor starters is recommended. The magnetic trip should be set above motor inrush current (typically 6-8x FLA).
Warranty & Compliance
Backed by ABB's 12-month warranty covering manufacturing defects. Factory-tested to IEC and UL standards with type-tested coordination tables available for selective protection design.
