Type 2 surge arrester BR-40 48

class IIDC powerfor power supplies

Module design, convenient installation, with easy electric maintains operation With working indication window. Built-in over current and over heat, temperature control open circuit technology The main module and the base are replaceable. Small creepage current, fast response time, remnant low voltage Mounting on symmetrical rail 35mm (EN60715). With remote connection, can realize remote control Application: It is mainly applicable for the Direct Current surge protection and over voltage protection in the fields of low voltage DC power supply. Applied to electrical systems to provide a discharge path to earth to save those systems’ components from being exposed to the high-voltage transients caused by the direct or indirect effects of lightning or power system anomalies. It is installed in the main power system at DC circuit, to protect against the indirect lighting current, direct lighting current or other instantaneous over voltage. Installation: When installed, in and out terminal of SPD will be corresponding connected with”+”,”-“pole of the DC power; ” PE ” is connected with grounding line;Connection way is by screwing tightly. After installation finished, check the wires if correct, switch on, then the SPD can be put into use.
