Insulation monitoring devices Ф4106, Ф4106А, Ф4106-С1 (Ф-4106, F4106) for 220/380 V networks with isolated neutral
Country: Ukraine · Model: F4106
Insulation monitoring devices Ф4106, Ф4106А and Ф4106-С1, often searched as Ф-4106 or F4106, measure insulation resistance in AC networks with isolated neutral at 220 or 380 V. The measuring range is 0.02–5 MΩ.

Description
The devices operate in networks under 220 or 380 V at 50, 60 or 400 Hz. They measure and monitor drops in insulation resistance in the range 0.02–5 MΩ. Alarm thresholds are 30, 50 and 500 kΩ. The device signals insulation loss before it leads to a single-phase fault, so the network need not be disconnected for testing. Isolated-neutral networks suit places where a first earth fault must not stop operation and insulation monitoring is mandatory: ship power networks, mines and underground workings, and autonomous 400 Hz power plants. The designation is written in several ways: Ф4106, Ф-4106, F4106, Ф4106А, Ф4106-С1. This is one device family.
How to choose
Choose the model and alarm threshold by network and alarm requirements: voltage 220 or 380 V, frequency 50, 60 or 400 Hz, and one of the thresholds 30, 50 or 500 kΩ. For differences between Ф4106, Ф4106А and Ф4106-С1, version, kit and verification, ask a USK ENERGY manager when ordering.
