OVRHMSU (Modular Series-Connected Unit) Surge Protective Device is engineered to protect hard-wired installations within or adjacent to electrical loads such as outdoor lighting, robotics, process automation systems, motors, HVAC systems, pumps, heaters, programmable logic controllers, and other point-of-use applications. Compact and powerful, the OVRHMSU employs MOVs in parallel arrays placed at the input and output terminals to guard these and other individual components against damaging electrical transients, high-frequency noise, and high energy disturbances. OVRHMSU provides 50 kA of surge protection for loads up to 24 A.
