Panel Mounted Surge Protection Devices
Address facility-wide surge suppression with panel mounted surge protection devices (SPDs). These high-energy protection products are a strong first line of defense against high-impulse transients. You’ll find our products offer a wide range of protection levels and configurations to meet your needs, including web-based monitors, multi-stage suppression systems, modular designs, and much more. Need help to find the best surge protection solutions? The Surge Protection Device Selection Tool helps you select SPDs for a broad range of applications from small data rooms to enterprise data centers.
The ASCO Model 425 Surge Protective Device uses thermally protected MOVs, is designed in a NEMA 4X enclosure, and is tested as a UL 1449 Type 1 device, so it can be placed on the line or load side of the main disconnect.
A surge protective device that offers high-end surge capability at a competitive price. The ASCO Model 430 uses thermally protected MOVs, provides EMI/RFI filtering in a package that focuses on basic features and reliable performance.
A modular surge protective device capable of diverting high-energy transients. The ASCO Model 460 incorporates either single or dual modules that contain multiple, large block MOVs.
The ASCO Model 510 Surge Protective Device offers continuous protection from damaging transients and electrical line noise, it utilizes patented circuitry to monitor the status of all protection modes, including neutral to ground. Excellent choice for retro-fit installations.
Repetitive life cycle capability, high-energy capacity and years of proven field experience allow us to confidently recommend the ASCO Model 560 Surge Protective Device for any “HIGH-RISK” location or “CRITICAL” process. A modular design with available surge current ratings from 160kA to 750kA per phase. Provides facility-wide surge suppression and EMI/RFI filtering at service entrance and distribution panels.
The ASCO 570 Surge Protective Device is a true hybrid, offering a coordinated multi-stage system of suppression, integrating the fast response time of the SAD (Silicon Avalanche Diode) modules with the high-energy capability of the MOV modules. Superior clamping at surge current ratings up to 375kA per mode or 750kA per phase.
