Product Description
Product Structural Characteristics
- Surge protective device for a port, under normal circumstances, the surge protector presents a high resistance state, when the grid line suffered indirect lightning and direct lightning effects or other transient overvoltage, surge protector in nanoseconds to achieve resistance to conductive Through, the transient energy will be leaked into the earth, and at the same time, the overvoltage will be limited to a certain level of protection. When the transient overvoltage disappears When the transient overvoltage disappears, the surge protector restores the high resistance state, so as not to affect the normal operation of the power grid.
- Surge protector for universal base plus protection module or zero-earth protection module (zero-earth protection module built-in gas discharge tube or graphite gap), can be easily combined into 2P, 3P, 4P. protection module for plugging, can be replaced.
- Surge protector built-in disengage. When the surge protector malfunctions or fails, the disengager disconnects the surge protector fromthe power system permanently, and indicates that the surge protector is not connected to the power system. The power system is permanently disconnected, and the indicator window shows the action indication from green to red. The green color indicates normal operation and the red color indicates a fault. green for normal operation and red for failure. In this case, the protection module must be replaced immediately and can be replaced quickly without a power failure.
Installation and Maintenance
- The surge protector is installed with 35mm standard rail, and the product is installed in the distribution box, distribution cabinet or box.
- The installation should be free of obvious impact and vibration.
- Surge protector is connected by copper wire, its cross section area is: soft wire .5~16mm2, hard wire 2.5~25mm2. Connection line should be as short as possible, the total length should be less than 0.5 m. Neutral wire using light blue wire, grounding wire using green and yellow (two-color). The neutral wire is made of light blue wire, and the ground wire is made of green and yellow (two-color) wire with a cross- section area of 4mm².
- Each pole of the surge protector must be set to protect, available small circuit breakers for current protection, small circuit breakers The breaking capacity of the small circuit breaker must be greater than the short-circuit current of the place, or fuse can be used.
