Description

The GE Magne Blast AM 4.16 75 1200A 4.76 kV is a medium‑voltage air circuit breaker engineered to deliver reliable protection and interruption performance for power distribution systems in industrial, commercial, and utility environments. Originally manufactured by General Electric, this breaker is part of the Magne‑Blast product line, which was widely used in metal‑clad switchgear designed for medium‑voltage applications.

Rated at 1200 amperes with a nominal voltage class of 4.76 kV, the GE Magne Blast AM breaker provides dependable overload and short‑circuit protection for three‑phase electrical circuits. Its solid mechanical construction and arc‑extinguishing design — based on the magnetic blow‑out principle — support consistent interruption of fault currents while safeguarding downstream electrical equipment and minimizing system downtime. The breaker uses air as the interrupting medium, with magnetic fields aiding arc elongation and cooling during fault clearing.

The GE Magne Blast AM is designed for installation in vertical‑lift metal‑clad switchgear assemblies where high reliability and serviceability are required. The breaker may include mechanisms such as solenoid or stored‑energy operated operating systems, supporting electrically operated or draw‑out configurations depending on the specific model and installation requirements. These features facilitate safer breaker operation, maintenance, and replacement without requiring full system shutdown.

With its combination of medium‑voltage capability, solid construction, and proven interruption technology, the GE Magne Blast AM 4.16 75 1200A 4.76 kV circuit breaker is suitable for industrial distribution panels, switchgear feeders, motor controls, and other environments where robust protection and long‑term system stability are essential.
