The Siemens SENTRON 3VA2063-6HM36-0AA0 is an H-class high breaking capacity molded case circuit breaker designed for industrial power distribution systems, delivering reliable protection against overload, short-circuit and earth fault conditions in factories, commercial buildings and infrastructure projects.

Protection Functions & Features

Equipped with the advanced ETU330 electronic trip unit, this MCCB offers comprehensive LIG protection with fully adjustable parameters:

• Overload Protection (L): Adjustable from 25A to 63A with 0.5s to 17s time delay, I²t characteristic curve
• Instantaneous Short-Circuit Protection (I): Adjustable from 1.5 to 12 times rated current (95A to 756A)
• Earth Fault Protection (G): Sum current detection on phase conductors, adjustable trip current 0.25 to 1×In (16A to 63A), trip time 0.1s to 0.3s

Maintains full rated current capacity from 40°C to 70°C without derating, ensuring reliable performance in high-temperature environments.
