Joint protection block (rheostat) JPB (R)

КИП-БСЗ

The utilizing of power resistors allows to make smooth adjustment of channels resistance, not using electrical connectors, without disconnecting the cathodic protection station.

A built-in instrument shunt allows to determine the channel current rate using a millivoltmeter.

JPB (R) protection against lightning overvoltage is provided by lightning protection device (varistor).
