Discription of production
control box
Use and performance
The control box is suitable for mining, enterprises, shopping malls, hotels, schools, airports, ports, hospitals, high-rise buildings, living quarters and other occasions, AC 50HZ, rated working voltage of AC 380V low-voltage power grid system, as power, lighting and power distribution For motor control, it is suitable for indoor wall-mounted and outdoor floor-mounted power distribution equipment. It is also used in the power system with AC 50HZ and voltage below 500V as fire-fighting pump control, submersible pump control, fire-fighting fan control, fan control, lighting power distribution control, etc. The control methods include direct start control, star delta step-down start control, autocoupling Various control methods such as step-down start control, inverter start control, and soft start control can also use isolation switches and fuse switches as isolation breaking points.
Electrical parameters
Rated working voltage AC 380V;
The working voltage of auxiliary circuit is AC 380V, 220V, DC 220V, 110V;
Rated frequency 50HZ
Rated insulation voltage 500V;
Rated working current 630A, 500A, 400A, 315A, 250A, 200A, 150A, 100A, 80A, 63A, 50A, 40A, 32A, 25A, 20A, 16A, 10A;
Short-circuit withstand current 10KA~35KA
Conditoin
1 The ambient temperature is not higher than +40°C, the average temperature in a 24-hour period is not higher than +35°C, and the lower limit of the ambient air temperature is -5°C;
2 The air is clean, and the relative humidity does not exceed 50% when the temperature is +40°C. A higher relative humidity is allowed at a lower temperature. For example, the relative humidity is 90% at +20°C. It should be considered that moderate condensation may occasionally occur due to temperature changes.
3 Pollution degree is 3
4 The altitude of the installation site shall not exceed 2000 meters;
5 Vertical installation on the floor, the installation inclination shall not exceed 5 degrees
6 The place where there is no violent vibration and impact, it is not enough to corrode the place such as the photoelectricity and components;
7 The transportation and storage temperature range is between -25°C and +55°C, and can reach +7-°C in a short time (not more than 24h);
8Special conditions of use shall be negotiated separately when ordering.
