Pure Differential Switch Type A-Sel 63A Idn 1A 4P ABB F428236
The pure differential switch, without magnetothermal releases, is an innovative device that guarantees high protection from dangerous leakage currents. It provides optimal safety in instrument adjustment operations, according to the CEI EN 61008-1 and CEI EN 61008-2-1 standards.
Secondary and primary protection
Pure differentials offer double protection. They protect people from dangerous indirect contacts, while the additional protection safeguards against the effects of direct contacts. All these safety measures comply with the CEI EN 61008-1 and CEI EN 61008-2-1 regulations.
Unique Features
- Without a built-in magnetothermal device: This means that pure differentials must be combined with suitable automatic switches or fuses to ensure protection against short circuits.
- Anti-disturbance APR versions: These are devices specifically designed to resist untimely trips caused by impulsive dispersions. This may be due to various maneuvers or atmospheric phenomena such as lightning.
Opt for the Pure Differential Switch Type A-Sel 63A Idn 1A 4P ABB F428236 to ensure maximum safety and functionality in your electrical system.
