Type 2 surge protector BR-40 110

class IIDC powerelectronic equipment

DC power surge protector. With working indication window. Compact design. For mounting: DIN-Rail. Pluggable module. The varistor have thermal disconnection devices. Application: Prevent damage from overvoltage DC that can be caused by lightning surge and other strong changes in electricity. 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. Protect sensitive electric and electronic equipment from transient voltage. Installation: It is connected in parallel on the line to be protected. After installation finished, check the wires if correct, switch on, then the SPD can be put into use.
