Magnetic-thermal motor circuit breaker TeSys GV5, 3-pole, 150A, Icu=36kA, lever GV5P150F

The TeSys GV5P150F motor circuit breaker is a reliable device designed to protect three-phase motors up to 75 kW at 400 V. Its robust construction and advanced protective features make it an ideal solution for both professional installers and end users, ensuring safe and efficient operation of power systems.

Features and Applications

This 3-pole circuit breaker combines thermal and magnetic protection functions, safeguarding motors against the effects of overloads, short circuits, and phase imbalance. The adjustable thermal trip setting range (70–150 A) allows precise tuning to match load characteristics, while the high short-circuit breaking capacity (Icu = 36 kA at 400 V AC) ensures rapid response during fault conditions. Lever-based operation provides convenient handling and clear visual indication of the device status.
