The main circuit adopts vacuum contactor, no arc, long service life and high
Adopting JDB digital protector, it has the functions of overload, short circuit,
breaking phase, leakage of main circuit and blocking.
It can be equipped with liquid level controller as a special switch for water level
Scope of application:
This series of electromagnetic starter is suitable for the ring of explosive mixture
gas such as methane and coal dust in the coal mine and its surrounding medium in
the environment. Mainly used for direct start or stop AC 50Hz, rated voltage up to
1140V, rated current to 200A mining
Flameproof three-phase asynchronous motor. For local control, remote control,
joint control and sequence control, the irreversible starter is available commutation
is performed at the stop time; reversible starter can perform frequent positive and
reverse operation on the controlled motor.
Rated voltage, alternating, 3-phase frequency (50±1) Hz, V 127, 220, 380, 660
Rated current of maximum releases, A 16
