The SPD1-B series electricity wells up the protector (to hereafter refer to as SPD) to be suitable in exchanging 50/60Hz, the rated voltage to power supply systems and so on 80V TT, TN-S, TN-C, IT, uses in when the thunderstroke the equipotential connection installs in 420A or 2P20B presses the intersection point, usually installs in the poling coil in low pressure power distribution cabinet place. SPD conforms to GB18802.1/IEC61643-1.
Product characteristic:
1. SPD is a port, guards against receives an electric shock the protection, the indoors type fixed installment, the voltage limit.
2. In SPD sets at the knock-out, when when SPD superheat, puncture expiration, the knock-out can automatic be separated from it from the electrical network, simultaneously gives The pilot signal. When SPD normal work the visible window demonstration green, after expires is separated from demonstrates red.
3. Uses the high quality import chip, the three-phase four module biggest enlargement electric current may reach 60kA.
