Scope of Application
The HR5 series fuse-switch disconnectors (hereinafter referred to as “switches”) are mainly used in distribution circuits and motor circuits with high short-circuit currents, rated voltage AC 380 V and conventional free-air thermal current up to 630 A. They serve as power switches, isolating switches, emergency switches, and for circuit protection, but are generally not used for direct making and breaking of a single motor.
This product complies with IEC 60947-3 and GB/T 14048.3 standards.
Main Parameters and Technical Performance
- Rated insulation voltage: 690 V
- Rated operational voltage: 380 V
- Rated operational current: 100 A, 200 A, 400 A, 630 A (four ratings)
- Mechanical endurance of the switch: 1400 operations (100 A, 200 A); 800 operations (400 A, 630 A)
- Electrical endurance of the switch: 200 operations (100 A, 200 A, 400 A, 630 A)
- Auxiliary switch (LX19K): rated operational voltage AC 380 V, rated thermal current 5 A, rated control capacity 300 VA
Normal Service and Installation Conditions
- Ambient air temperature not higher than +40°C and not lower than -5°C.
- Installation altitude not exceeding 2000 m.
- Humidity: At a maximum temperature of +40°C, the relative humidity of the air shall not exceed 50%. Higher relative humidity is permitted at lower temperatures (e.g., 90% at 20°C). Appropriate measures shall be taken against occasional condensation caused by temperature variations.
- Pollution degree of the surrounding environment is degree 3.
- The switch shall be installed in a location free from significant vibration, shock vibration and rain/snow exposure. The installation site shall be free from explosive media, and the medium shall contain no gases or dust sufficient to corrode metal or damage insulation.
