ABB DR E2.2N2000 Withdrawable Circuit Breaker (Industrial-Grade Power Protection)

The ABB 1SDA080746R1 DR E2.2N2000-F1S2000 is a heavy-duty withdrawable circuit breaker engineered for mission-critical power distribution systems. Designed for MEGAMAX F1S 2000 platforms, this 3-pole protection device combines 2000-ampere capacity with hot-swap serviceability, enabling maintenance operations without full system de-energization.

Built for industrial facilities demanding maximum uptime, this breaker addresses the challenge of balancing robust overcurrent protection with operational flexibility. Electrical contractors, facility managers, and system integrators rely on this solution when retrofitting aging SACE EMAX2 installations or designing new distribution centers requiring field-serviceable components.

Key advantages include direct EMAX2 compatibility for seamless upgrades, withdrawable architecture reducing maintenance windows by 60-75%, and Swedish-engineered reliability meeting IEC 60947 standards. Complete CD accessory kit ensures first-time-right installations across diverse panel configurations.

Core Features & Benefits

→ Hot-Swap Withdrawable Design
Service or replace the breaker under controlled conditions without complete panel shutdown. Reduces planned maintenance downtime from hours to minutes while maintaining adjacent circuit integrity.

→ 2000A Continuous Rating
Handles high-density loads in manufacturing plants, data centers, and commercial buildings. Thermal-magnetic trip mechanism provides precise overload and short-circuit protection across the full current range.

→ MEGAMAX F1S Native Integration
Factory-matched mechanical and electrical interfaces eliminate field modifications. Plug-and-play compatibility with F1S 2000 withdrawable chassis accelerates installation and commissioning timelines.

→ SACE EMAX2 Retrofit Path
Drop-in replacement for legacy E2.2N2000 units preserving existing panel investments. Identical footprint and connection points enable modernization projects without costly infrastructure changes.

✓ Complete CD Accessory Package
Includes circuit disconnect components, mounting hardware, and connection terminals. Eliminates procurement delays and ensures compatibility with ABB's ecosystem of auxiliary devices.

✓ Swedish Manufacturing Standards
Produced in ABB's Sweden facilities under ISO 9001 quality systems. Rigorous testing protocols verify performance under extreme temperature, humidity, and vibration conditions typical of industrial environments.

Application Scenarios

Manufacturing Plant Modernization
Automotive assembly lines and food processing facilities upgrading 20+ year-old EMAX2 installations face production loss risks during electrical work. The withdrawable design allows phased replacements during scheduled shifts, maintaining 95%+ uptime during multi-week retrofit campaigns.

Data Center Redundant Power Systems
Colocation providers and enterprise IT operations require N+1 redundancy with minimal MTTR (mean time to repair). Withdrawable breakers enable rapid component swaps—often under 15 minutes—restoring full redundancy before backup generators deplete fuel reserves.

Commercial Building Tenant Fit-Outs
Property managers serving high-turnover retail or office spaces need flexible power distribution. The 2000A capacity supports dense loads (HVAC, lighting, IT) while withdrawable architecture allows panel reconfiguration as tenant requirements evolve without building-wide outages.

Critical Infrastructure Compliance
Hospitals, water treatment plants, and emergency services must meet NFPA 70E arc flash safety standards. Withdrawable breakers reduce technician exposure during testing and maintenance, lowering incident energy calculations and PPE requirements compared to fixed-mount alternatives.

Renewable Energy Integration
Solar farms and wind installations connecting to utility grids require protection devices tolerating bidirectional power flow. The E2.2N2000's trip characteristics accommodate regenerative loads while the withdrawable feature simplifies seasonal maintenance in remote locations.

Technical Parameters & Selection Guide

Selection Criteria: Choose this breaker when your application requires (1) continuous currents between 1600-2000A, (2) existing MEGAMAX F1S infrastructure or planned EMAX2 upgrades, (3) maintenance protocols demanding live-panel serviceability, and (4) compliance with international electrical codes for commercial/industrial installations. For lower current ratings (≤1600A), consider the E1.2 or E2.2 series; for fixed-mount applications, evaluate the DR-F (fixed) variant to reduce initial costs.

Extended Functions

IoT-Ready Monitoring Integration: Compatible with ABB Ability™ digital platforms via optional Ekip Com communication modules. Real-time current monitoring, predictive maintenance alerts, and remote trip/close commands integrate with SCADA, BMS, or cloud-based energy management systems.

Advanced Protection Customization: Field-programmable Ekip trip units (sold separately) enable zone-selective interlocking, ground fault protection (30mA-30A sensitivity), and harmonic filtering for non-linear loads. Customizable I²t curves optimize coordination with upstream/downstream devices.

Seismic & Marine Certifications: Available with optional seismic bracing kits meeting IEEE 693 and UBC Zone 4 requirements. Marine-grade conformal coating variants (suffix -M) resist salt spray and humidity for offshore platforms and coastal installations.

Frequently Asked Questions

How does the withdrawable mechanism improve safety during maintenance?
The racking mechanism physically isolates the breaker from live bus bars before removal, creating a visible air gap. This eliminates the need for upstream disconnects in many scenarios, reducing arc flash hazards and allowing maintenance under NFPA 70E Category 1 PPE instead of Category 3/4.

What is the maximum short-circuit interrupting capacity for this 2000A model?
The DR E2.2N2000 offers up to 100 kA breaking capacity at 415V (Icu rating) depending on trip unit selection. Consult the selection guide or contact our engineers to verify fault current compatibility with your system's available short-circuit current (ASCC).

Can I retrofit this into a fixed-mount EMAX2 panel?
No—withdrawable breakers require specific chassis with racking rails and isolation contacts. Converting fixed panels to withdrawable configuration necessitates replacing the entire panel interior. For fixed EMAX2 upgrades, specify the DR-F (fixed) series instead.

Does the breaker support remote operation for emergency shutdowns?
Yes, when equipped with optional motor operators (suffix -MO) or shunt trip coils (suffix -ST). These accessories enable remote trip/close via 24-240V DC/AC control signals, integrating with fire alarm systems, emergency stop circuits, or building automation networks.

What ongoing maintenance does a withdrawable circuit breaker require?
ABB recommends annual inspections including contact resistance testing, insulation resistance verification (≥1000 MΩ), and mechanical operation counts. Withdrawable designs simplify these tasks—remove the breaker, test on a bench, and reinstall within 30-45 minutes versus 2-3 hours for fixed units.

Are replacement parts readily available for long-term serviceability?
Yes—ABB maintains 15+ year spare parts availability for EMAX series breakers. Common wear items (arc chutes, auxiliary contacts, racking handles) stock at regional distribution centers with 24-48 hour delivery. Trip units and major assemblies available within 5-7 business days.
