ABB E2.2N1600 Air Circuit Breaker (Industrial-Grade 1600A Protection System)

The ABB E2.2N1600 air circuit breaker delivers enterprise-level electrical protection for high-demand industrial installations. This 1600-ampere ACB from the Emax 2 product line integrates microprocessor-based trip control, multi-protocol connectivity, and field-proven reliability to secure power distribution networks in manufacturing plants, commercial complexes, and critical infrastructure facilities.

Designed for electrical contractors and facility engineers managing medium-voltage switchgear assemblies, the 1SDA080745R1 model addresses overcurrent protection, selective coordination challenges, and real-time system monitoring requirements. Its modular architecture supports both new construction projects and retrofit applications where legacy equipment requires performance upgrades.

Key differentiators include 100kA short-circuit interrupting capability at 415V, programmable LSIG protection curves with thermal memory, and hot-swappable communication modules for seamless SCADA/BMS integration—enabling predictive maintenance workflows that reduce unplanned downtime by up to 40%.

Core Features & Technical Advantages

Microprocessor-controlled protection with adjustable L (0.4-1.0×In), S (1.5-10×In), I (2-15×In), and G (0.2-1.0×In) functions. Thermal memory prevents nuisance tripping during sequential motor starts while maintaining fault sensitivity.

→ 100kA Breaking Capacity
Verified to IEC 60947-2 standards with Ics=100% Icu rating, ensuring consistent performance across the entire service life. Suitable for installations with high available fault currents up to 690V AC.

→ Multi-Protocol Communication Ready
Native support for Modbus RTU/TCP, Profibus DP, and DeviceNet via plug-in modules. Transmits 50+ electrical parameters including voltage harmonics, power factor trends, and contact wear indicators for condition-based maintenance.

✓ Withdrawable Design Option
Rack-out mechanism allows breaker removal without de-energizing busbars, reducing maintenance windows from hours to minutes. Interchangeable with fixed-mount configurations using adapter kits.

✓ Zone Selective Interlocking (ZSI)
Coordinates with upstream/downstream devices to isolate faults in <100ms, minimizing arc flash incident energy and protecting adjacent circuits during short-circuit events.

✓ Extended Operating Range
Functional from -25°C to +70°C ambient temperatures with derating curves for tropical and arctic installations. Salt mist and vibration-resistant construction meets marine/offshore certifications.

Application Scenarios & Problem-Solving Capabilities

Heavy Manufacturing Main Distribution
In automotive assembly plants and steel mills, the E2.2N1600 serves as the primary protection device for 1600A main feeders supplying robotic welding cells, induction furnaces, and conveyor systems. Selective coordination with downstream MCCBs prevents plant-wide shutdowns when individual machine faults occur, maintaining production continuity.

Data Center Critical Power Paths
Protects UPS output distribution and generator tie-ins where power quality monitoring is essential. Real-time voltage sag detection and harmonic analysis data feed into DCIM platforms, enabling proactive load balancing before IT equipment experiences brownout conditions.

High-Rise Commercial Switchgear
Manages riser feeds in office towers and shopping centers where tenant metering and demand response programs require granular energy data. Built-in kWh metering eliminates separate instrumentation costs while providing billing-grade accuracy (Class 1 per IEC 62053-21).

Water Treatment & Pumping Stations
Withstands high inrush currents from large motor loads (pumps, blowers, clarifiers) while providing ground fault protection for wet environments. IP54-rated enclosures available for outdoor installations with direct weather exposure.

Marine Propulsion & Auxiliary Systems
Meets DNV-GL and ABS type-approval requirements for shipboard electrical systems. Shock and vibration resistance per IEC 60068-2-6 ensures reliable operation during rough sea conditions and emergency maneuvering.

Technical Parameters & Selection Criteria

Selection Guidelines: Choose the E2.2N1600 when your application requires rated currents between 1400-1600A with fault levels exceeding 65kA. For installations with lower fault currents (<50kA), consider the Tmax XT series for cost optimization. Verify busbar compatibility and ensure adequate panel depth for withdrawable execution if hot-swap maintenance is required.

Advanced Integration Capabilities

Energy Analytics & Reporting
The embedded power meter captures voltage/current waveforms at 128 samples per cycle, detecting transient events that standard meters miss. Export CSV logs via Ethernet for power quality audits, harmonic compliance verification (IEEE 519), and utility billing reconciliation.

Arc Flash Risk Reduction
When paired with ABB's REA arc flash relays, the breaker achieves <50ms total clearing time under bolted fault conditions—reducing incident energy levels below 4 cal/cm² in many configurations and lowering PPE requirements from Category 3 to Category 1.

Cybersecurity Features
Role-based access control with 256-bit encryption for remote parameter changes. Audit trails log all setting modifications with timestamp and user ID, meeting NERC CIP compliance requirements for critical infrastructure protection.

Delivery Timelines & Service Commitments

Standard Lead Time: 3-5 business days for in-stock configurations (fixed mount, standard trip unit). Custom builds with specialized accessories ship within 10-15 business days after order confirmation.

Frequently Asked Questions

How do I verify compatibility with existing ABB switchgear panels?
The Emax 2 series maintains dimensional compatibility with Emax 1 frames for most configurations. Provide your panel model number (e.g., UniGear ZS1, ArTu) and we'll confirm mounting hole patterns and busbar interface specifications. Adapter plates are available for non-standard installations.

What's the difference between LSIG and LSIGU protection functions?
LSIG provides Long-time, Short-time, Instantaneous, and Ground fault protection. The "U" variant adds unbalance/phase loss detection for motor protection applications. For general distribution, LSIG is sufficient; specify LSIGU when protecting critical rotating equipment.

Can this breaker handle generator paralleling applications?
Yes, with proper coordination settings. The adjustable short-time delay (S function) allows selective tripping during generator synchronization transients. Consult factory application notes for reverse power protection and load-sharing configurations.

What communication speed does Modbus RTU support?
Configurable from 9600 to 115200 baud. For installations with long cable runs (>500m), use 19200 baud with twisted-pair shielded cable to minimize data errors. Modbus TCP operates at standard Ethernet speeds (10/100 Mbps).

How often should contact resistance be measured?
ABB recommends annual micro-ohm testing for breakers operating above 80% rated current. The trip unit's diagnostic menu displays cumulative I²t thermal stress—schedule testing when this value exceeds 75% of rated capacity or after interrupting faults >50% Icu.

Are replacement parts available for field service?
Yes, all wear components (contacts, arc chutes, operating mechanisms) stock as service parts with 24-48 hour shipping. Contact kits include pre-calibrated assemblies to maintain original factory settings without specialized tools.
