The GE AKR 6D 100 LSG 4000A MicroVersa DO is a high‑capacity low‑voltage air circuit breaker engineered to deliver dependable protection, precise fault interruption, and flexible operation for industrial, commercial, and utility power distribution systems. Manufactured by General Electric, this breaker combines rugged mechanical construction with advanced MicroVersa electronic trip technology to safeguard critical electrical networks and support high performance in demanding environments.

Rated at 4000 amperes, the AKR 6D 100 breaker is designed for heavy‑duty applications such as primary feeder circuits, large switchgear assemblies, motor control centers, and major distribution panels where reliable fault clearing and system coordination are essential. Its LSG (Long‑time, Short‑time, Ground‑fault) MicroVersa trip unit offers configurable protection settings that enable precise detection and interruption of overloads, short circuits, and ground faults, improving safety and selectivity across the electrical system.

The DO (Draw‑Out) design provides operational flexibility and maintenance convenience by allowing the breaker to be safely removed or reinserted without shutting down the entire power system. This makes it an excellent choice for facilities that require minimal downtime and easy servicing, such as large industrial plants, data centers, hospitals, and commercial complexes.

Built with a durable contact system, effective arc‑extinguishing mechanisms, and robust operating components, the GE AKR 6D 100 delivers consistent performance and long service life even under repeated switching and heavy duty cycles. It can be integrated with accessories such as auxiliary contacts, shunt trips, undervoltage releases, and communication modules for advanced monitoring and automation applications.

Overall, the GE AKR 6D 100 LSG 4000A MicroVersa DO air circuit breaker offers powerful high‑current protection, flexible draw‑out operation, and advanced electronic trip functionality, making it an ideal solution for mission‑critical electrical distribution systems where reliability, safety, and maintainability are paramount.
