AC SPDs Surge Protective Device SPD Surge Protection Device for Power Supply Systems
Surge protective device SPD surge protection device is a protective device for limiting transient voltages by diverting or limiting surge current and is capable of repeating these functions as specified.
Surge protection is a cost-effective solution to prevent downtime, improve the system and data reliability and elimination of equipment damage due to transients and surges for both power and signal lines. It is suitable for any facility or load (1000 volts and below). Typical SPD applications within industrial, commercial and residential include:
- Power distribution, control cabinets, programmable logic controllers, electronic motor controllers, equipment monitoring, lighting circuits, metering, medical equipment, critical loads, backup power, UPS, HVAC equipment
- Communication circuits, telephone or facsimile lines, cable TV feeds, security systems, alarm signaling circuits, entertainment center or stereo equipment, kitchen or household appliances
