Features & Benefits

1. High Performance & Protection
   With a 2000 A continuous current rating and a 42 kA short-circuit breaking capacity, this breaker is well-suited for heavy-duty protection in critical systems. 

2. Smart Trip Control
   The EKIP / DIP-LI R electronic trip unit offers flexible and precise control over overload and fault conditions, enabling adjustable protection settings for both long-term and instantaneous faults.

3. Robust Mechanical Construction
   Designed with a fixed architecture, rear horizontal connections, and a durable build, this circuit breaker is built for long service life and minimal maintenance. 

4. Auxiliary Contact Support
   Comes fitted with 4 auxiliary (change-over) contacts, enabling status signaling (open/closed) and external interlocking.

5. Eco-friendly Design
   As part of ABB’s EcoSolutions, it is designed for high recyclability (EN45555 standard) and has an environmental product declaration (EPD). 

6. Safety & Compliance
   Meets international safety and low-voltage switchgear standards, making it suitable for a wide range of industrial applications.
