Arrester
SRM400V474KBH is a surge arrester made by Mersen (formerly Ferraz Shawmut). It is an AC Nominal Voltage of 400V, with an Impulse Voltage kV of 474, and Rated Continuous Current (8/20us) Icn 70kA. It has a PTC fuse with a hold current of 6A. This model is suitable for any application with an incoming voltage of 400V and an impulse discharge rating of 474kV. It offers reliable and cost-effective protection against transient overvoltage, lightning strike, and other power surge events. The fuse feature provides the overcurrent protection needed in many applications to protect downstream equipment.
