ABB MWD-06 Surge arrester MWD series oxide arrester in stock

The ABB MWD-06 is a member of the MWD series of surge arresters, which is a silicone-rubber-insulated, gapless metal-oxide surge arrester. Here is a detailed introduction:

Technical Characteristics

• Rated Voltage: Usually 6 kV, suitable for AC systems with a nominal voltage of around 6 kV.

• Continuous Operating Voltage: It can continuously operate at a voltage of up to 4.8 kV, ensuring stable performance during normal operation.

• Nominal Discharge Current: The nominal discharge current is 10 kA, which allows it to effectively handle large - amplitude over - voltage surges caused by lightning or switching operations.

• Response Time: The response time is 100 μs, which can quickly respond to over - voltage surges and limit the duration of over - voltages.

• Residual Voltage: When discharging, it can limit the residual voltage to a relatively low level to protect the connected electrical equipment. For example, the residual voltage at 8/20 μs wave shape may be around 18 kV.

• Excellent Non-linear Characteristics: Using metal - oxide (MO) resistors as the core component, it shows excellent non - linear volt - ampere characteristics8. Under normal voltage, the resistance is very high, and the leakage current is only in the micro - ampere range8. When an over - voltage occurs, the resistance decreases rapidly, allowing a large current to pass through and discharge the over - voltage energy8.
