Overvoltage protection B 63-48
Overvoltage arrester in two-wire technology in 0/4 … 20 mA circuits
for two-wire circuits, direct mounting in the cable entry of the field device
Application area
The overvoltage arrester B63-48 limits excess voltage in signal cables. The arrester protects the electronics of the connected instruments effectively against the effects of overvoltages.
Your benefit
- Simple mounting of the cable gland of the field device
- High reliability even with impermissible excess voltages
