Decoupling cells
Réf. DIP-029
Decoupling cells to protect insulating joints and provide AC mitigation: they block the cathodic protection DC current while draining AC faults.
Description
Decoupling cells protect insulating joints (kits or monobloc) and provide alternating-current mitigation by blocking the flow of cathodic protection DC current. On an installation, they reduce unwanted current consumption on adjacent earths.
They withstand a continuous current (AC/DC) of 100 A, an AC fault current of 2 to 50 kA (50/60 Hz, 30 cycles) and a lightning current of 100 kA (8×20 and 10/350 µs), with a DC blocking threshold of -3/+1 V or -2/+2 V optional, over a -45 to +65 °C range. The flameproof enclosures (T6, NEMA 4X, Class 1 Div 2, IP67) comply with UL, CSA, ANSI, ISA, ATEX and IECEx standards. They are installed in a box or directly on the insulating joint lugs.
