Surgelogic offers a full range of externally mounted SPDs. These units are designed to provide surge suppression from service entrance panels to 

point-of-use equipment. 

US and Canadian UL ® Listed to UL 1449 3rd Edition and UL 1283 5th Edition. Complies with requirements of NEC ® Article 285 and CSA 22.2 

No. 8-M1986 as appropriate. Complies with UL 96A 12th Edition Master Label requirements for Lightning Protection Systems. 

• 10 modes of protection 

• 200 kA SCCR 

• EMI/RFI filtering 

• Audible alarm with enable/disable switch, dry 

contacts, and surge counter standard 

• Indicator LEDs; normal (green) and fault condition (red) for each phase 

External SPD Options: 

• Sine Wave Tracking Module. Sine Wave Tracking (SWT) circuitry provides enhanced EMI/RFI filtering of -54 dB at 100 kHz and establishes the 

power surge clamping window relative to the sine wave voltage to increase performance at distribution and branch panel applications. 

• Integral Switch. The integral switch provides a mechanical means to electrically isolate the entire surge suppressor before opening the 

enclosure door to facilitate servicing of the unit’s components. 

• Remote Monitor. This option displays the alarm status of the surge protective device up to 1000 feet from the unit. 

• Flush Mount Kits. Flush mounting kits can be used on 120–240 kA EMA and EBA series devices. Devices with integral switch require a 20 inch flush 

mounting collar. 

External Modular Assembly (EMA) SPDs 

EMA SPD products feature a design based on individual phase modules for a flexible, cost effective way to achieve superior surge suppression at every 

level of the electrical distribution system. Modularity results in lower life cycle costs and fast, easy service or replacement.
