Pure Differential Switch AC Type In 40A Idn 300mA 4P ABB F427819
Our Pure Differential Switch Type AC In 40A Idn 300mA 4P ABB F427819 is an essential tool designed to protect against indirect and direct contacts. This switch guarantees protection according to the CEI EN 61008-1 and CEI EN 61008-2-1 standards, ensuring the protection of people in every situation.
Functionality of Pure Differentials without Magnetothermal Releases
Since they do not have a built-in magnetothermal device, pure differentials need to be protected against short circuits. This can be achieved by using appropriate automatic switches or fuses integrated into the system.
Anti-disturbance APR versions
Our anti-disturbance APR versions are devices designed to resist untimely trips given by impulsive dispersions due to maneuvers or atmospheric phenomena, such as lightning. These devices guarantee an interruption-free user experience in any environmental condition.
