VAL-MS 400/3+0/VF-FM - Type 2 surge arrester
Surge protective device combination, 3-channel, for installation on NS 35/7,5, with remote indication contact (FM) as changeover contact, voltage 400 V AC
- Quality proven millions of times over in the widest range of applications
- Rapid installation with bridges, thanks to industry-standard overall width of 1 HP
- 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
Technical Specifications
General
| Note | Burst test up to 4 kV passed according to DIN EN 61000-4-4. |
