GE WPS 40 WavePro 4000A EO DO LSIG

The GE WPS 40 WavePro 4000A EO DO LSIG is a high‑capacity low‑voltage air circuit breaker engineered to provide superior protection, precise fault interruption, and flexible operation in demanding industrial, commercial, and utility power distribution systems. Manufactured by General Electric, this breaker combines advanced electronic protection technology with robust mechanical design to safeguard critical electrical infrastructure and support high‑performance environments.

Rated at 4000 amperes, the WavePro 40 breaker is ideal for main feeder circuits, switchgear assemblies, motor control centers, and large distribution panels where reliable fault clearing and system continuity are essential. Its LSIG (Long‑time, Short‑time, Instantaneous, Ground‑fault) trip functionality offers configurable protection settings to match system coordination requirements, ensuring accurate response to overloads, short circuits, and ground faults while optimizing selectivity with upstream and downstream devices.

The EO (Electrically Operated) configuration enables remote switching, enhancing operational flexibility and integration with automated control systems, while the DO (Draw‑Out) design allows the breaker to be safely withdrawn for inspection, maintenance, or replacement without disrupting power to the entire system—reducing downtime and improving serviceability.

Equipped with a durable contact system, arc‑extinguishing mechanism, and rugged operating components, the WavePro 40 breaker delivers consistent performance even under frequent switching and heavy electrical stress. Its modular construction supports the addition of accessories such as auxiliary contacts, shunt trips, undervoltage releases, and communication modules for remote monitoring and integration into advanced power management systems.

Designed for reliability and ease of maintenance, the GE WPS 40 WavePro 4000A EO DO LSIG is widely used in industrial plants, data centers, commercial facilities, utilities, and critical infrastructure projects where safety and uptime are paramount. Its combination of advanced protection technology, flexible operation, and robust design makes it a dependable solution for modern electrical distribution needs.
