Product details
Product Introduction
1、 Scope of application
NHL 30-100 series visual lockable isolation switch（Equipped with a visual window isolation switch）Suitable for distribution and control circuits with AC 50Hz or 60Hz, rated operating voltage of 230V or 400V and below, for no-load switching between the upper part of the 100A distribution device and the power supply. Mainly used as the main switch for terminal appliances, it can also be used to control various types of motors, low-power appliances, lighting, and other places. The mechanical and electrical lifespan is 10000 times, of which the electrical lifespan is 6000 times.NHL 30 with visual window isolation switchMeets the requirements of standards such as GB14048.3 and IEC947-3.
2、 Model and specifications
3、 Operating environment and working conditions
The ambient air temperature ranges from -5 degrees Celsius to+40 degrees Celsius, with an average temperature not exceeding+35 degrees Celsius.The altitude shall not exceed 2000m.
The relative temperature of the atmosphere plus 40 degrees Celsius does not exceed 50%, and the wettest month is 90%.
The pollution level is level II.
◆ Use category AC-22A.
The installation form adopts TH35-7.5 steel installation rail installation, and the other installation surfaces have a vertical inclination angle of not more than five degrees with the body.
4、 Structural characteristics
NHL 30 with visual window isolation switchThe contact system adopts a double breakpoint direct acting structure, and two sets of parallel and contact connections are selected for high current, which not only increases the current capacity but also fully utilizes the electric force compensation. At the same time, the spring energy storage of the handle operating mechanism enables rapid switching. Overcoming the impact of slow manual operation speed, greatly improving the possibility of work, the contact opening and closing status has a prominent package label display, which can prevent misoperation and improve safety.5、 Main technical parameters

6、 Installation and use
During installation, insert the installation rail according to the position shown in the diagram, push up the handle to connect, and the indicator sign is red; Pull down the handle to disconnect, and the indicator label is green.
The power supply inlet should be connected from above the switch, and the lower end should be connected to the outlet. The copper wire should be tightened and not loose or exposed outside the terminal.
Before powering on, manually operate the switch several times, which should be flexible, reliable, and free of obstruction.
The NHL 30 visual lockable isolation switch must not be affected by rainwater during use, storage, transportation, and other processes.
The NHL30 visual lockable isolation switch can withstand (short-circuit) currents under abnormal circuit conditions for a certain period of time, and can also withstand appropriate overloads without frequent switching, but cannot be used to disconnect fault currents.
