The device is able to protect motor branch circuits from overload, short circuit and phase loss. The working voltage of this circuit breaker is 690 VAC, and its rated current is 25 A. It is one of the important spare parts of Schneider coolers in data centers.

The 641-0838-Z is a 24V power supply with a current of 2A and a power of 45W. The 641-0838-Z power supply is used in the Schneider brand INROW ACRC 301S cooler to generate 24 VDC from the 240 VAC input. Thanks to the switching system, the dimensions of the power source are very small (compared to linear power sources). Only two very small heat sinks have been used for the AC switch and a regulator. It is one of the important spare parts of Schneider machines in data centers.

Schneider Won-0279 float level switch is a simple, passive and functional product that is used in various industries. This switch uses surface control devices. It has advantages such as simple structure, no complex circuit, and smaller volume than the general mechanical switch. One of the prominent features of the product is its suitable materials, and the attention to the shape and nature of the liquid or the pressure that comes into contact with it. In other words, this switch is widely used in industries such as data center coolers, shipbuilding, production equipment, petrochemical, food industry, water purification equipment, etc. When the pressure is applied, the Won-0279 float level switch generally activates a relay and controls the system.

Schneider relay RSB2A080B7 is used in chillers and data center chillers. This relay has two open and closed contacts, which are controlled by 24 VAC, and 50 and 60 Hz frequency. It can pass 8 A current at an ambient temperature from -40 to +40 °C. The operating voltage of the relay is 19.2 to 36 VAC. Its nominal insulation voltage is 400 volts, and its instantaneous withstand voltage is 3.6 kV. The maximum voltage of the switch is 300 VDC and the minimum voltage of the switch is 12 volts. The RSB2A080B7 relay can operate 18,000 times per hour at no load, which decreases to 600 times per hour when under load. The operation time of RSB2A080B7 relay for activation and reset is 20 milliseconds. It is one of the important spare parts of Schneider machines in data centers.

Houper metal detector, part number HOU-WM6001 has many uses in entrances and public places. The LEC display can clearly display information such as the type and the amount of metal, and its location in the person\'s body without the need to directly view it on the device. It can also count the number of people who pass through the gate, and store the information about people, objects and metals. By using the Single zone feature, you can remove unnecessary noises. The anti-interference mechanical technology deal with mechanical interferences.  This technology benefits from the vibration absorption and analysis systems to identify and prevent mechanical interference. This artificial intelligence device also has the ability to learn and predict.
