Meba surge protection device MBS3-65

Specification

Meba surge protection device MBS3-65

□MBS3-65 series surge protective device (hereinafter called SPD) is
suitably used in the IT, TT, TN-C, TN-S, TN-C-S and etc power supply
system of AC 50/60Hz, rated voltage up to 380V, to protect from direct
and indirect lightning impulse and other transient over voltage. As per the conditions of IEC61643-1:1998-02 standard, Class I surge protective device, it is category B surge protective device.
Operation Elements
Single pole structure, single pole or three poles combined SPD available.。
□ 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 separated from network, it will show red color. It can adopt Kelvin wiring
mode.
□ Large current carrying capacity, fast response time, low residual voltage.
Installation
□ Category B surge protective device (SPD), used in the connection between equal pot-ential electrodes while thunder occur.
□ To be mounted: between LPZ0A or LPZ0B zone and LPZ1 zone, adopts 35mm standard mounting rail. The cross sectional area of multi-strand soft copper conductor: 2.5~35mm2.
□ Generally to be installed in low voltage main incoming distribution panel, overhead incoming.As required, the user can assemble single pole or three poles surge protective device freely.
□ Generally to be installed in low voltage main incoming distribution panel, earthing wire shall be dual color multi-strand soft copper conductor more than 16 mm2.
