-SPD meets with GB18802.1/IEC61643-1 standard
Installation
- MBS6140R is mounted between LPZ1 or LPZ2 zone and LPZ3 zone. The cross sectional area of multi-strand soft copper conductor to be connected: 2.5~ 35 mm2. It is used in distribution boxes of living house, computer center, communication equipment, electronic equipment and control equipment or nearest
socket box.
- MBS6140R is mounted between LPZ0B or LPZ1 zone and LPZ2 zone. The cross
sectional area of multi-strand soft copper conductor to be connected: 2.5~ 35 mm2.
The Contact
Contact for remote communication can be provided for SPD, the contact has one pair for transferring, 11 as middle position, 12 and 11 opened under SPD acting, 14 and 11 closed under SPD acting, 11 and 14 as NO contact. If one or more of modules of SPD is invalid, the contact will be closed and send fault signal.
