SDD1-150-275 is a 2-phase surge arrester, a power line surge arrester installed on a DIN bar, 3-stage protection MOV technology LN, L-PE, N-PE rated voltage 230V , with LED display of activity, response time <5ns , mandatory standard AS/NZS1768-2007 and AS/NZS3000. Specifications include: - SDD1-150-275 has LED showing operating status: if the lightning arrester does NOT have LED display but only 01 Blue box is displayed until the arrester is burnt out, the Red box will appear. , that is, this device is made without an electronic board and impedances to handle lightning filters, but only includes 1 MOV to help short circuit like a CB. - SDD1-150-275 has a lightning response time of < 5 ns : if the lightning arrester has a Slower response time (eg: > 10 ns), it is very easy to ignite the devices. electronic board of television - computer etc.. - SDD1-150-275 has a normal operating voltage of 220V-230V equal to the operating voltage of the circuit breaker (or CB / MCCB / Aptomat) in Vietnam: if the lightning protection device has a normal operating voltage 240V or more (Since 1950, the voltage in Europe has been raised to 230V instead of 220V), the lightning protection function is NOT suitable for the voltage in Vietnam is 220V because when the voltage is > 230V, a short circuit will occur first. Power supply of the Circuit Breaker (or CB / MCCB / Aptomat) - SDD1-150-275 Withstand lightning current 150kA/phase (8/20µs), total lightning current Imax = 300kA: the smaller the lightning current withstand device, the less effective the protection will be
