Mora AC 2pole SPD Surge Protection Device (AES-2040) 40kA-385vAC

The Mora AES-2040 AC 2-Pole 40 kA Surge Protection Device (SPD) is  DIN-rail mounted surge protector designed to shield single-phase AC electrical systems from harmful voltage spikes and transient overvoltages caused by lightning strikes, switching events, or grid disturbances. It’s rated for 385 V AC operating voltage with a maximum continuous operating voltage of 415 V AC, and features a high discharge capacity (20 kA nominal, 40 kA peak) to divert surge energy away from sensitive equipment before it can cause damage. With a fast response time (< 25 ns) and broad operating temperature range (-40 °C to +85 °C), this SPD is built for durable, reliable protection in residential, commercial, and industrial distribution panels, helping to extend the life of appliances and electronic devices by preventing surge-related failures.
