Modular Relay ( 3 modules DIN 17,5 mm) for controlling the insulation resistance in a single/three phase system insulated from earth up to 500 V ac and 48 V dc, with possibility of setting the tripping threshold and fault signalling.
RI-F22 / RI-R22
These devices allow insulation monitoring on earth of electric networks voltage 24÷ 230 Vac.
RI-F48 / RI-R48
The devices allow the insulation monitoring to earth of electric networks in alternate and direct-current till 48 V isolated.
RI-R38
This device allow insulation monitoring on earth of electric networks voltage 24 ÷ 440 Vac.
RI-R11
The devices allow permanent monitoring of insulation of electrical networks in direct-current current isolated on earth.
