The following are the core technical specifications of the B 62-30 W for selection and procurement reference.
| Parameter | Value | Unit |
|---|---|---|
| Maximum continuous operating voltage Uc | 30 | V DC |
| Nominal discharge current In | 5 | kA |
| Maximum discharge current Imax | 10 | kA |
| Voltage protection level Up | ≤ 60 | V |
| Response time tA | ≤ 25 | ns |
| Operating temperature range | -40 ~ +80 | ℃ |
Installation and Wiring
Correct installation and wiring are key to ensuring overvoltage protection effectiveness. Please follow these steps:
- Confirm that the system is powered off and comply with relevant safety regulations.
- Install the B 62-30 W on a DIN rail close to the protected equipment.
- Connect the input (IN) and output (OUT) terminals according to the manual markings, ensuring correct polarity.
- Connect the grounding wire; the grounding resistance should be less than 4Ω.
- After checking that the wiring is correct, restore power and observe the indicator status.
Note: Live wiring is strictly prohibited, and the grounding wire should be as short and thick as possible to reduce residual voltage.
Maintenance and Precautions
To ensure long-term reliable operation, regularly check the status of the overvoltage protection module.
- If the indicator window turns red, it indicates that the module has failed and needs to be replaced promptly.
- It is recommended to perform a routine inspection once a year, and increase inspection frequency after the thunderstorm season.
- When replacing the module, use the same model or products with equivalent parameters.
- Non-professionals should not disassemble or repair.
