Arrester NZ-7C

Arrester NZ-7C

An arrester protects measuring instruments and transducers from induced lighting. In lighting-prone areas, the induced voltage of lighting traveling through the cables of measuring instruments or switch boxes can damage instruments and transducers. When placing measuring instruments and transducers, connection of NZR-7B／NZ-7C on cabling between an instrument and a switch box or NZ-6B on cabling between a transducer and switch box will protect the instrument and transducer by allowing induced current to pass to the ground.

Arrester NZ-7C
Features
  • Either soldering or NDIS plug is possible for cable connection
  • Contains a commercial power supply (built-in varistor) terminal, allowing power supply for a switch box to be connected easily

  • Specifications
    Type NZ-7C
    Applicable instruments Data logger: TDS-630, TDS-540, TDS-530
    Switching Box: ASW-50C, ASW-30C, SSW-50D
