Section 6: Surge Protective Devices (SPDs)
Externally Mounted SPDs
Surgelogic™ EMA and EBA series SPDs offer a full range of externally mounted surge suppression solutions, designed for service entrance panels to point-of-use equipment. They are US and Canadian UL® Listed to the UL 1449 standard and comply with NEC® Article 285 and CSA 22.2 No. 8-M1986. They also comply with UL 96A 12th Edition Master Label requirements for Lightning Protection Systems.
Key features include a 10-year product warranty, 10 modes of protection, EMI/RFI filtering, audible alarm with dry contacts and surge counter, and indicator LEDs for normal (green) and fault (red) conditions. They also have a 200 kA SCCR and are UL 1449 Type 1 for use in both Type 1 and Type 2 applications.
EMA Series SPDs
EMA SPD products feature a design based on individual phase modules for flexibility and cost-effectiveness. Modularity allows for lower life cycle costs and faster service or replacement.
EMA SPD Options:
- Enhanced Filtering Module: Sine wave tracking circuitry provides enhanced EMI/RFI filtering and establishes the power surge clamping window relative to the sine wave voltage.
- Disconnect Switch: An integral switch provides a mechanical means to electrically isolate the surge suppressor before opening the enclosure door.
