Ω Link is a ready-to-use flexible prefabricated shunt made in tinned copper braid, coated with PVC insulation.Ω Link is the quickest and most convenient solution to make 125 to 630A electric connections.The connection terminals are made of pressed tinned copper tube. Their size is designed looking at the poles of the most widespreadswitchgears on the market, thus making it possible to get the best electric contact possible.Hole diameter allows, on one side, optimization of the electric contact in relation with the switch pole; on the other end, the possibility tohave a universal contact to bar distribution systems.Made in PVC, the insulation meets all the electric specifications required for use in L.V. environment. Maximum continuous working temperature is 105°C.

The best alternative to cable connections.

ADVANTAGES EXCELLENT ELECTRIC PARAMETERSReady-to-use connections: no preventive operation is required - Excellent electric insulation- Extreme flexibility compared to a cable with similar cross-section - Better contact surface- Volume reduction inside the panel board - Better ampacity at equal cross-section compared to a cable- Weight reduction and/or reduced cross-section at the same rated current- Great time savings - Reduced heating due to the lack of crimped connections and to - No cable to cut to measure better ampacity- No stripping of cable heads - Excellent short-circuit resistance- No lug to buy- No crimping needed

RANGECross-sections: from 25 mm2 to 240 mm2

Lengths: from 230 mm to 930 mmRated ampacity: from 125 A to 630 A
