Specification

Meba lightning arrester MBD2-40 is in absorbing foreign advanced technology research and development on the basis of new replaceable type SPD. SPD is suitable for use in ac 50/60Hz ac rated voltage 380V, below the power supply system of indirect or direct lightning, the lightning influence or other instantaneous over voltage protection.
SPD has common mode (MC) and differential mode (MD) protection way. SPD accord with GB18802.1 /IEC61643-1.

Parameter

Meba lightning arrester MBD2-40

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 separated 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.
