Fuse Bases For Square Pipe Fuses With Knife Contacts

Product Overview

This series fuse is suitable for AC 50Hz, rated voltage to 690V, rated current to 1250A, for overload and short circuit protection in electrical wiring(gG/gL).Because of different melting tablets,it also may derive for protecting the semiconductor device and its complete set installment from short circuit(aR/gR/gs/gtr)、as well as the electric motor from short circuit(aM). The rated breaking capacity up to 50kA. They conform to GB13539.2 and IEC60269-2
