Protection Functions & Trip Characteristics

The advanced electronic trip unit provides comprehensive protection:

• L (Long-time): Overload protection with adjustable time-current curves (0.4-1.0 x In), I²t or thermal memory characteristics
• S (Short-time): Short-circuit protection with adjustable delay (1.5-10 x In), enabling selective coordination
• I (Instantaneous): High-magnitude fault protection (2-15 x In) for immediate tripping
• G (Ground Fault): Earth leakage protection (0.2-1.0 x In) with independent time delay settings
• Zone Selective Interlocking (ZSI): Minimizes fault clearing time through coordinated protection schemes

Industrial Applications

The Emax 2 E2.2N1600 excels in high-power distribution scenarios:

• Manufacturing Facilities: Main distribution boards (MDB) and motor control centers (MCC) supplying heavy machinery, production lines, and material handling equipment in automotive, steel, and chemical plants
• Data Centers: Critical power distribution for UPS systems, PDUs, and IT load protection where reliability and monitoring are paramount
• Commercial Buildings: Main switchgear in high-rise offices, shopping malls, and hospitality complexes requiring intelligent load management and energy metering
• Infrastructure Projects: Substations, water treatment plants, and transportation hubs demanding robust protection and remote monitoring capabilities
• Marine & Offshore: Shipboard electrical systems and offshore platforms where space optimization and harsh environment resistance are critical

Engineering Solutions & System Integration

Selective Coordination: The E2.2N1600's adjustable short-time delay function enables selective coordination with downstream protective devices, isolating faults at the lowest possible level while maintaining power to unaffected circuits. This minimizes downtime and simplifies troubleshooting in complex distribution networks.

Energy Management Integration: Built-in power metering capabilities measure voltage, current, power factor, energy consumption, and harmonics. Integration with building management systems (BMS) or SCADA platforms via Modbus or Profibus enables real-time energy monitoring, demand response strategies, and cost allocation across multiple tenants or production areas.

Predictive Maintenance: The trip unit continuously monitors operating conditions including contact wear, number of operations, thermal stress, and fault history. Maintenance alerts and diagnostic data accessible through communication interfaces enable condition-based maintenance scheduling, reducing unplanned outages and extending equipment lifespan.

Arc Flash Mitigation: When integrated with arc flash detection systems, the Emax 2 can achieve ultra-fast tripping (within 50ms) to minimize arc flash incident energy, protecting personnel and equipment. The breaker's high breaking capacity ensures safe interruption even under severe fault conditions.

Common Technical Questions

Q: What is the difference between fixed and withdrawable execution?
A: Fixed execution breakers are permanently mounted in the switchgear, while withdrawable (plug-in) versions can be removed from the panel without disconnecting cables, facilitating maintenance and testing. The 1SDA080745R1 configuration should be verified based on your specific application requirements.

Q: Can this breaker be retrofitted into existing ABB Emax 1 panels?
A: Emax 2 breakers are designed with backward compatibility for many Emax 1 installations, though specific mounting dimensions and auxiliary device compatibility should be verified. Our technical team can assist with retrofit feasibility assessments and any required adapter kits.

Q: How do I configure the electronic trip unit settings?
A: Trip unit parameters are programmed using ABB's Ekip Connect software via USB or Bluetooth connection. Settings can be password-protected to prevent unauthorized changes. We recommend documenting all settings and performing coordination studies before commissioning.

Q: What communication protocols are supported for integration with our SCADA system?
A: The Emax 2 supports Modbus RTU (RS-485), Modbus TCP/IP (Ethernet), Profibus DP, and DeviceNet through optional communication modules. The breaker provides comprehensive data including real-time measurements, alarm status, and historical event logs.

Q: What maintenance is required for this circuit breaker?
A: Routine maintenance includes visual inspection, contact resistance measurement, insulation testing, and mechanical operation verification. ABB recommends maintenance intervals based on operating cycles and fault interruptions. The trip unit's diagnostic features provide guidance on when maintenance is needed.
