Product Description
Mining Explosion proof Starter (QJZ-6-12)

1. Function

It is ideal for mines with explosive gases (Methane) and coals, and it is used in AC
50Hz, 1140(660)V power supply circuit, to control start, stop, reverse rotation and doubleswitching
Of 6-12 circuits 3-phase AC asynchronous inductive motors or 3-6 circuits AC
Double-winding and double-speed motors. It also can protect motors and their power
Supply circuits. Therefore, when it is integrated in K J2000 mine electric power automatic
Control and comprehensive measurement and monitor system to realize automatic control
On power supply equipments in mining area. The starter has all English LCD touch screen
Display that has highly stable performance and is highly reliable for perfect man-machine
Conversation function.

2. Characteristics

2.1 All English LCD touch screen display;
2.2 Pull-down menu setting;
2.3 Standard RS 485/232 communication interface is attached;
2.4 Various protective functions for over-current, short-circuit, undervoltage, phase loss,
Current leakage, over-voltage and 3-phase imbalance etc;
2.5 Real-time display of 3-phase current, system voltage, operating status of circuit, on-line
Status of circuit and fault types etc;
2.6 Function of faults searching and faults recording;
2.7 It is attached in KJ2000 mine electric power automatic control and comprehensive
Measurement and monitor system to realize telemetry, telecommunication, remote
Control and remote regulation.

3. Technical Parameter

3.1 Rated voltage: 1140(660)V
3.2 Rated frequency: 50HZ
