(A) Main switch 4P 0-1 63A

NH4 Switch disconnectors (known as Isolators) can be used in Chint consumer units, Chint distribution boards or as standalone devices to provide circuit protection. Ensures that the electrical circuit is completely de-energised for service or maintenance. Designed to match NB series MCBs/RCBOs. Din rail mountable.
