IP BC 60/FM-350 2kV
Article Nr. : 550523
The arresters can be installed at the transition 0A to 2 according to the lightning protection zones concept. Single-pole lightning and transient (switching-) surge voltage arrester for the protection of low-voltage electrical distribution systems by industrial, commercial and private use.
- Combined Arresters Type 1+2 (Class I+II)
- Test standard: IEC 61643-11 / EN 61643-11
- On the basis of hermetically sealed rare-gas-filled spark gaps
- Protection level ? 2 kV
- Remote signalling contact: break contact
- High insulation resistance
- No blow-out vents, thus, not requiring any safety clearance to other installations
- Optional remonte contact (FM) requiring no additional space
- EAC certification
