GE AKR 10D 100 LSIG 4000A MicroVersa

The GE AKR 10D 100 LSIG 4000A MicroVersa is a high-capacity low-voltage air circuit breaker designed to provide reliable protection and control for industrial, commercial, and utility power distribution systems. Part of the proven AKR series from General Electric, this breaker combines robust mechanical design with advanced MicroVersa electronic trip technology, delivering precise fault detection and superior operational performance in demanding environments.

Rated at 4000 amperes, the AKR 10D 100 LSIG is engineered for high-current applications in large switchgear assemblies, motor control centers, and critical electrical distribution panels. Its LSIG (Long-time, Short-time, Instantaneous, Ground-fault) MicroVersa trip unit enables configurable protection settings for overloads, short circuits, and ground faults, ensuring optimal coordination with upstream and downstream devices while enhancing system safety.

The breaker features a draw-out construction, allowing safe removal for inspection, maintenance, or replacement without disrupting the entire switchgear system. Electrically or manually operated configurations provide installation flexibility and ease of integration with automation and monitoring systems. Its rugged contact system and arc-extinguishing technology ensure long operational life, reliable fault clearing, and consistent performance under repeated electrical stresses.

Ideal for high-demand industrial and commercial applications, including power plants, manufacturing facilities, data centers, and large commercial buildings, the GE AKR 10D 100 LSIG 4000A MicroVersa delivers high reliability, safety, and operational efficiency. Its modular and service-friendly design supports reduced downtime, easy upgrades, and integration with advanced power management solutions.
