Surgelogic Type EMA systems are external surgical protection devices with a focus on individual phase modules. With a surge current rating of 240,000 Amps, enhanced EMI/RFI filtering of -54 dB at 100 kHz is possible to increase performance at distribution and branch panel applications. Using a mechanical system to electrically isolate the entire surge suppressor, servicing of units components is simplified. Being modular in design, this unit is able to achieve superior surge suppression at every level of the electrical distribution system. This unit provides surge suppression from service entrance panels to point-of-use equipment. This surge protector is also certified by UL and CSA.
