ABB F427823 Pure Differential Switch
A high quality differential switch, the AC type in 63A Idn 500mA 4P from ABB F427823 offers reliable protection and safety assurance. These pure differential switches are free of thermal-magnetic trip units, offering excellent protection against indirect contact and additional protection against direct contact, in line with the CEI EN 61008-1 and CEI EN 61008-2-1 standards.
Short circuit protection
Since they do not have a built-in magnetothermal device, pure differentials require additional protection against short circuits. This protection can be ensured by using automatic switches or suitable fuses.
Anti-disturbance APR versions
To ensure even more efficient performance, the anti-disturbance APR versions have been specifically designed to be immune to sudden trips. These can be caused by impulsive dispersions due to maneuvers or atmospheric phenomena, such as lightning.
- Safety guarantee: Protection of people from indirect contact and additional protection from direct contact.
- Compliance with standards: In line with CEI EN 61008-1 and CEI EN 61008-2-1 standards.
- Short circuit protection: Short circuit protection through appropriate circuit breakers or fuses is essential.
- Immunity from nuisance trips: The anti-disturbance APR versions offer resistance to nuisance trips due to impulsive dispersions or atmospheric phenomena.
