IEC indoor Sulfr hexafluoride gas circuit breaker HD4 - ABB

Thanks to the Sulfr hexafluoride autopuffer breaking technique, the HD4 circuit breakers do not generate operating overvoltages, and are therefore also highly suitable for retrofitting, upgrading and enlarging older installations where the insulating materials for the motor, cable, etc. may be particularly sensitive to dielectric stresses.
