PowerBreak 2000A Air Circuit Breaker – Core Protection for Critical High-Capacity Distribution

Where system reliability and capacity converge at the highest level—be it a 2500kVA transformer secondary, a mission-critical data center’s main bus, or a heavy industrial plant’s power backbone—conventional protection reaches its limit. The PowerBreak 2000A Air Circuit Breaker is engineered for this scale. More than a switch, it is the intelligent, adaptive sentinel of your high-capacity electrical infrastructure. Combining a massive 2000A frame with an interrupting capacity of up to 200kA, it is built to withstand and clear the most severe faults. Integrated with a sophisticated digital brain, it delivers not just protection but comprehensive system visibility, advanced energy management, and seamless grid integration, making it the cornerstone of modern, resilient, and efficient power distribution.

Core Engineering & Intelligent Performance

1. Unmatched Fault Interruption & System Security
Feature: Features an advanced multi-stage arc quenching chamber with double-break technology and a precision-engineered, high-speed, spring-driven operating mechanism. Achieves an Ultimate Breaking Capacity (Icu) of 200kA at 415V AC, with a Service Breaking Capacity (Ics) equal to Icu per IEC standards.
Benefit: Provides the highest level of system integrity. Protects massive capital investments in transformers, switchgear, and connected machinery from catastrophic damage due to short-circuit events, ensuring business continuity even under extreme electrical stress.

2. Nexus IQ™ Advanced Digital Trip System
Feature: The core intelligence is the Nexus IQ trip unit, a modular computing platform offering:

• Adaptive Protection: Zone-Selective Interlocking (ZSI) for faster, coordinated tripping; customizable protection curves for generator, cable, and motor protection.

• Advanced Power Quality Suite: Continuous monitoring of total harmonic distortion (THD up to the 63rd harmonic), voltage dips/swells, unbalance, and transient capture.

• Predictive Health Analytics: Monitors contact wear, insulation resistance, mechanism timing, and temperature to forecast maintenance needs.
  Benefit: Transforms protection into proactive system management. Enables condition-based maintenance, optimizes protection coordination for selective tripping, and provides forensic data for event analysis.

3. Engineered for High-Availability & Safety
Feature: Robust, full-draw-out design with motorized racking option (plug & drive). Clear, fortified positional interlocks (Connected, Test, Disconnected, Withdrawn) and integrated, high-resolution ground-fault protection down to 1% of sensor rating.
Benefit: Maximizes uptime and personnel safety. Enables safe isolation and maintenance without de-energizing entire switchboards. The sensitive ground-fault protection is critical for systems with high-resistance grounding, preventing arc-flash hazards.

4. Cybersecurity & Seamless Digital Integration
Feature: Equipped with a Cybersecurity-hardened communication gateway featuring dual, independent Ethernet ports with configurable firewalls, role-based access control, and event logging. Natively supports IEC 61850 (GOOSE messaging), Modbus TCP, DNP3, and OPC UA.
Benefit: Future-proofs your investment for IIoT and smart grid applications. Enables secure, real-time data exchange with SCADA, DCIM (Data Center Infrastructure Management), and cloud-based analytics platforms while protecting against unauthorized access.

Technical Specifications
