Type 2 surge protection device, Surge voltage arrester, VAL-MS
[Specifications]
・Mounting method: DIN rail (top hat rail) 35 mm
・Construction size: 4 modular spacing
[Features]
・Easy testing and insulation measurement, thanks to pluggable protection modules
・Suitable for use in insulation-monitored systems due to combination of varistor and gas discharge tube free of leakage current
・Can be used in applications with increased insulation strength, e.g., railway technology
