Product Description
(one)Application
QJZ - 120/1140 (660) mining flameproof vacuum electromagnetic starter, mainly used in coal mines and other surrounding media containing methane and other mixed gas environment. Applicable to AC 50Hz, rated current to 200A, 120A, 80A, rated voltage 1140V, 660V line, direct or remote start and stop mining ftaxneproof three squirrel cage motor. It also has the functions of leakage blocking, overload protection, phase failure protection, under voltage protection, wind power locking, communication interface and so on. Can also be reversed when stopping.
(two)Features
The starter has many functions, such as loss of voltage, over voltage, overload, short circuit, phase failure, leakage and so on.
