Meba lightning arrester types MBS100

Meba lightning arrester types MBS100 series surge protective device (hereinafter called SPD) is suit-able for the IT, TT, TN-C, TN-S, TN-C-S and etc power supply system of AC 50/60Hz, rated voltage 380V and below, to protect from lightning impulse and other transient over voltage, it is applicable in class I lightning proof system where there has higher danger of lightning strikes As per the conditions of IEC61643-1:1998-02 standard, Class I surge protective device, it is category B surge protective device.

Operation Elements
□ Fast response time: less than 25ns
□ Low limited voltage
□ Large current carrying capacity
□ Normal state: white color, invalid state: red color
□ Kelvin wiring mode available.
□ Category B surge protective device (SPD), used in the connection between equal potential electrodes while thunder occur.
□ Generally to be installed in low voltage main incoming distribution panel, overhead incoming.
□ To adopt 35mm standard mounting rail for SPD mounting.
□ When to place an order, please indicate the model, specification and quantity of SPD.
□ It shall adopt 10~35mm2 copper conductor to be connected with SPD, earthing wire shall be dual color multi-strand soft copper conductor more than 16mm2.
The Contact
SPD can provide the NO contact for remote communication, if one or more modules of SPD is invalid, the NO and NC contact will be closed and send fault information.
