Automatic changeover switch NXZM-250S/4B 250A NXZM series integral ATS (Chint) The NXZM series automatic transfer switch is designed to automatically switch from one power source to another to maintain normal power supply to the load circuit. It is suitable for working with three-phase four wire overhead power lines. This type of line with redundant neutral grounding conductors exists in industrial facilities and general networks (multi story buildings, residential areas, etc.). The NXZM series covers a range of models from 63 to 800 A. This device can operate stably under difficult working conditions, such as decreased heat and humidity, extremely low or high temperatures, salt spray formation, etc. Multiple modes of operation Basic input and self-service refund. When the voltage drops, the load will automatically switch from the backup input to the power supply. When the voltage is restored at the main input terminal, the device will automatically switch the load back to the power supply from the first input terminal. Two equivalent inputs. This operating mode assumes that the primary input and backup input are under equal conditions. If there is no voltage on the first input, the load switches to the second input. Even if the voltage at the first input terminal recovers, it will continue to be powered by it. That is to say, there is no self return. Meanwhile, if necessary, you can manually switch at any time. The operating mode of the generator. It assumes that the generator set serves as a backup power source. In this mode, additional control functions will be activated. In addition to switching to backup power, the NXZM series integral ATS also provides signals to start and stop the generator. Meanwhile, the control unit can be used to independently set switches or signal time settings. equipment characteristics Run in "site to site" or "network to generator" mode. It can be switched from one collective network to another, or from the power grid to a backup generator. This greatly expands the application scope of the NXZM series integrated ATS. Automatic and manual movements. The power transfer from one input to another can be done not only automatically, but also manually. To achieve this, simply rotate the control handle on the device body. Network parameter indication. The current status of the device is indicated by indicator lights that emit signals. With the help of a digital display screen, you can find the current parameters and other relevant information of two inputs. The direct and feedback functions used in conjunction with the fire protection system. It allows you to interact with the control system of fire extinguishing, warning, and evacuation lighting circuits. High judgement ability. The maximum breaking capacity of NXZM series models reaches 50 kA, which is higher than the performance of many other similar integral ATS. Protection function Overvoltage protection. Voltage monitoring of main and backup power sources. Automatically switch when overvoltage occurs. Adjust the switch time delay. Undervoltage protection. Monitor the voltage parameters of two input terminals. Switch to another input at low voltage. Adjustable voltage set point and conversion time delay. Lack of phase protection. If voltage disconnection or phase failure is detected, it will switch to another input. Overload protection. Detect overcurrent in the circuit and transfer the load power to another input. Short circuit protection. Automatically switch when short-circuit current occurs. The overload and short-circuit currents of both input terminals are monitored. Design Features Overall design. The integrated structure of Chint NXZM series ATS makes it simple and fast to integrate into the distribution panel. In addition, the integrated ATS operates more reliably and is less susceptible to environmental influences (the casing can prevent dust, dirt, and water splashes). Compact body size. The new functional layout makes it possible to significantly reduce the size of the device. The manual control handle is located on the right side. The display unit is placed on the lid of the candy stick. This makes it possible to reduce the width of the hull. Detachable display unit. It allows you to place it on the cabinet door to intuitively control the current operating mode, the status of two inputs, the operating voltage value, and other parameters. It can control the operation of equipment without entering the interior of the cabinet. The device comes with an extension cable for connecting the display unit. Ergonomic handle. It is used for manually switching modes. The shape of the handle and its position on the right side of the device help to grip comfortably and elevate the user experience to a higher level.
