Model: 120-3Y-M3-4-06-A-SS

Special Features:

Surge protection device; voltage 120v/208v three phase wye; max continuous operating voltage 150v; discharge current 20ka; voltage protection rating l-g, n-g, 700v, l-l, l-n 1200v; max surge current 140ka; max lightening current 7.5ka; response time [1ns; stainless steel nema 4x; 12"x12"x8"; long duration surge perform 2ms 500a 250hits. This is a form-fit-function alternative for existing nsn 5920-01-513-4576 which is corroding badly at sites with salt air exposure. This item includes a stainless-steel enclosure and is intended as a suitable alternative for corrosive environments

Properties:

An item specifically designed to absorb and consume surges of voltage such as that resulting across contacts when breaking a circuit having an inductive load or a burst of static across a telephone receiver. It is connected in parallel with the item it is protecting. It may be made up of metallic rectifier cells or semiconductor devices connected back-to-back which may or may not be shunted by a capacitor. It may also be a single rectifier cell or semiconductor device shunted by a capacitor. Excludes metallic rectifiers which are rated for rectifying capabilities and all single unit semiconductor devices not shunted by a capacitor. For items perfoming this function by use of voltage sensitive resistors, see resistor, voltage sensitive. See also cutout disk, protective.
