Surge Protective Devices (SPDs)
Surge Protective Devices (SPDs)
A surge protector (or surge suppressor) is a device designed to protect electrical equipment from voltage spikes.

Surge protectors block or short to ground any unwanted voltages that pass a specific threshold. This limits the voltage that is allowed to pass through to connected equipment, devices or appliances.

Surge protectors are typically installed in distribution or control panels to protect connected industrial equipment. Their efficacy is determined by their peak voltage rating and response time. Heavy-duty protectors, for heavy machinery, are designed to dissipate thousands of Joules with rapid response times; smaller protectors can effectively protect control components and communications equipment at lighter loads.

ST-MODULAR Series Image
  • Easy Installation or Retrofit
  • DIN-rail Mountable
  • Fail-safe, Self-protected Design
  • Remote Indicator (Optional)
  • Visual Indicator
Surge-Trap Modular Surge Protective Device (SPD) is a no-fuse, fail-safe surge suppressor featuring Mersen's patented TPMOV® technology inside. The modular SPD is UL 1449 3rd Edition approved. It is DIN-rail mountable featuring a fail-safe self-protected design, visual indicator, and a small footprint. A remote indicator option provides status to critical control circuitry. The Surge-Trap Modular SPD has a high short circuit rating and a thermally protected MOV, which eliminates the need for additional overcurrent protection devices.
  • IP20 Finger-safe Design
  • Small Footprint
  • No Additional Overcurrent Protection Devices Required
Surgitron III Series Image
  • Listed to UL 1449 3rd Edition for a Type 1 SPD Application

  • Medium Duty
STV25K Series Image
  • Compact and Narrow Design Maximizes Panel Space
  • Low Clamping Levels for More Effective Protection
  • Easy Access Terminal Screws for Quick Mounting and Installation
  • 50,000 Amps of Surge Protection
  • Sine Wave Tracking and All Mode Protection Provide Consistent and Reliable Protection on All Electrical Paths
The STV25K series provides point-of-use protection, at the dedicated equipment level, against damaging transients. Ideal for installation in electronic control cabinets found in harsh industrial environments such as the factory floor or at remote locations. These devices provide 50,000 amps of surge protection, sinewave tracking, LED status indication and form "C" dry contacts. This DIN Rail series also provides protection on all electrical paths.
  • Thermal Fusing Prevents MOV Overheating caused by Excessive Current Levels
OVR-TYPE2 Series Image
Over 80 % of transient surges are caused by internal sources such as load switching and normal equipment operations. The installation of ABB OVR UL 1449 3rd edition pluggable AC DIN rail SPDs will combat these surges and provide protection to valuable equipment and help keep an operation up and running. This new product range is approved as Type 4 recognized components and is usable in Type 2 applications. These products are of the same high quality as ABB UL 1449 2nd edition devices, with improved safety as a result of additional testing required by the UL 1449 3rd edition standard. Installation at branch panels, control panels and terminal equipment is recommended to provide the most complete protection.
The OVR DIN rail SPDs utilize fast acting metal oxide varistor (MOV) technology to limit overvoltage to values compatible with the sensitive equipment connected to the network.
End of life indicator - This feature is standard on all ABB pluggable OVR DIN rail surge protectors. Each cartridge is equipped with a mechanical indicator which is green when the SPD is operational and protecting the system, and turns red when it has reached end of life. When this occurs, the cartridge must be replaced to guarantee protection.
The ability to efficiently maintain equipment is a key focus topic for industrial facilities. For this reason, ABB OVR DIN rail SPDs (excluding data line products) now utilize pluggable cartridges. Should one or more cartridges reach end of life, the electrical circuit does not have to be isolated, nor does the whole device have to be removed. Simply pull the dead cartridge from its housing and plug in a new one.
