The Emerson Network Power 440 is a non-modular, surge protective device that incorporates the same design platform as the 460 SPD; high-energy capable, thermally protected large block MOVs and a similar assortment of accessories. The 440 is ideal for use in distribution and sub-distribution applications and its non-modular construction allows it to be installed in areas where space is limited.
