Pure Differential Switch AC Type In 25A Idn 300mA 4P ABB F427818
The pure differential switch type AC In 25A Idn 300mA 4P ABB F427818 is an unparalleled safety device. These switches guarantee effective protection from both indirect and direct contacts, in compliance with the CEI EN 61008-1 and CEI EN 61008-2-1 standards.
Protection without Magnetothermal Trips
Without built-in thermal-magnetic trip units, pure RCDs require protection against short circuits. This is ensured by appropriate circuit breakers or fuses.
Anti-disturbance APR versions
The APR anti-perturbation versions of the pure differential switch are devices carefully designed to resist untimely trips. These potential trips are often caused by impulsive dispersions that may be due to operational maneuvers or atmospheric phenomena, such as lightning.
