Rated conditional short circuit current (Inc) 1500A tested with Hager MTN110 6kA B curve MCB. instead i would like to wire it independent of the light switch and using the isolator as a wall switch. i have checked the reference posts which shows how to wire to a light switch. Secondly, the disconnecting switch will cause arcing during the pulling and closing process, burn the contacts, and increase the contact resistance. 1 Hi after advice from some members here i have bought a 3 pole isolator switch to connect to my timer extractor fan. The reason for the increase in contact resistance is: the repulsive force of the contact between the blade and the knife tip is very large, and the knife edge is not tightly closed, which causes surface oxidation and increases the contact resistance. Tips: What causes the contact resistance of the isolating switch to increase?
