Lauritz Knudsen Air Circuit Breakers (ACBs) are engineered for superior power protection and advanced system management. Built with a modular and robust design, these ACBs deliver high breaking capacities and comply with global standards, including IS/IEC 60947-2. Offering a wide current range from 400A to 6300A and short-circuit breaking capacities up to 100kA at 415V, they ensure maximum safety and reliability. Key features include easy upgradability, flexible configurations (fixed and draw-out types), manual and electrical operation options, and compatibility with multiple busbar arrangements. Designed for seamless integration, Lauritz Knudsen ACBs support industry-standard communication protocols for remote monitoring, enabling smart connectivity. Their user-friendly design ensures quick installation and simplified maintenance, making them the ideal choice for modern power distribution systems.
LK’s ACBs are designed for all kind of environments with high temperature, humidity, and dust presence with Pollution Degree 4 protection, ensuring consistent performance without compromise.
User-friendly modular accessories enable easy customization and on-site changes like conversion from fixed to draw-out or manual to electrical versions.
Microprocessor-based releases with true RMS sensing and OLED display provide comprehensive protection against overload, short circuit, earth fault, and more, with options for Zone Selective Interlocking (ZSI), Restricted Earth Fault, Dual Protection Set Groups and Energy Reduced Maintenance Settings (ERMS) etc.
Features like front-accessible release settings, maintenance positions on draw-out types, screw less arcing contacts, and lockable shutter mechanisms enhance operational safety and serviceability.
