Product Features

Adaptive Design

Field Upgradeability with Ekip Aware: The next-generation Ekip Aware trip unit enables on-site customization, making it easy to upgrade measurement, protection, and communication functions as system requirements evolve — minimizing downtime and maximizing flexibility.
Digitally Simplified Interaction: The redesigned HMI offers faster access through a simplified menu structure, ensuring efficient interaction with the breaker. In combination with the EPiC mobile app and Ekip Connect software, it allows complete monitoring, control, and data analysis from a smartphone or laptop.
Advanced Communication Architecture: Supports high-speed Ethernet, Ekip Supply EVO Modbus TCP, and daisy-chain networking. Wireless connectivity through Bluetooth Low Energy (BLE) and Near-Field Communication (NFC) allows secure, on-the-spot access to breaker data. Communication is available in 7 different protocols including IEC 61850 and Profinet.
Enhanced Interlock Mechanisms: Improved mechanical interlocks provide best operational safety and control, with a simplified design to reduce installation time and guarantee performance over time.
Backward Compatibility: Retains the same overall dimensions, fixing points, connection terminations, and electrical performances as the widely known Emax 2, allowing straightforward migration without the need for system redesign.

Reliability & Performance

Power Management Strategies: Actively maintains system stability and optimizes performance even under demanding conditions. The breaker’s custom logics feature enables tailored control strategies for complex applications, ensuring intelligent response to fluctuating power loads and system demands.
Power Quality and Measurement: Achieves class 0.5 accuracy for active power and energy in accordance with IEC 61557-12. Improves load monitoring, enables precise sub-billing, and enhances system management without additional meters or sensors — optimizing space and reducing installation costs. The data logger provides detailed event tracking for root-cause analysis and ongoing power quality management.
Asset Management and Predictive Maintenance: Enhances asset reliability through condition-based and predictive maintenance strategies. An internal network of sensors continuously monitors key metrics, proactively identifying potential issues and forecasting maintenance needs. Key capabilities include real-time asset monitoring, advanced health indexing, optimized accessory maintenance, and temperature monitoring under any ambient and load condition.

Cybersecurity & Safety

Advanced Cybersecurity (IEC 62443-4-2): Designed according to the stringent IEC 62443-4-2 cybersecurity standard, covering embedded devices, software, and components. Security features include secure firmware updates with anti roll-back, secure storage with anti tampering, dedicated module portfolio with anti spoofing, secure USB and BLE communication, and role-based access management (Owner, Admin, Engineer, Operator, Viewer). Wireless communication via Bluetooth and NFC also requires user authentication.
Expanded Protection: Offers comprehensive protection for people and assets, including rapid arc-flash detection (up to 12 sensors per circuit breaker), Remote Racking Device (RRD) for safe breaker racking without exposing personnel to arc flash risks, and enhanced safety measures such as new key locks, padlocks, and Reduced Energy Let-Through (RELT) protection.
