Meba lightning surge protection MBS2

Meba lightning surge protection MBS2

□ MBS2series surge protective device (hereinafter called SPD) is developed no basis of absorbing foreign latest technology, used in power supply system of AC 50/60Hz, rated voltage 380V and below, to protect from direct and indirect lightning impulse and other transient over voltage.
□ SPD has two protection modes: MC and MD。
□ SPD is in compliance with GB18802.1/IEC61643-1 standards
Operation Elements
□ SPD has built-in disconnector, when SPD is invalid due to overheating or breakdown, the disconnector can automatically separate SPD from the network, meanwhile send an indication signal. The visible window show white color in normal service, if to be sepa-rated from network, it will show red color.
Installation
To be mounted between LPZOB or LPZ1 zone and LPZ2 zone, adopts 35mm standard mounting rail. The cross sectional area of multi-strand soft copper conductor: 2.5~ 35 mm2.Every pole of SPD shall be protected by fuse or mini circuit breaker. As required, the user can assemble single pole or three poles
surge protective device freely.
