FAQ
Why Do We Need Surge Protective Devices?
Surge protective devices (SPDs) are essential in protecting electronic equipment from the harmful effects of transient overvoltage that can cause damage, system downtime, and data loss. In many cases, the cost of equipment replacement or repair can be significant, particularly in mission-critical applications such as hospitals, data centers, and industrial plants. Circuit breakers and fuses are not designed to handle these high-energy events, making additional surge protection necessary. While SPDs are specifically designed to divert transient overvoltage away from the equipment, protecting it from damage and prolonging its lifespan. In conclusion, SPDs are essential in the modern technological environment.
Surge Protective Device Guidelines
Surge Protective Devices (SPDs) play a critical role in protecting electrical and electronic equipment and to ensure proper protection, it is essential to follow guidelines for selecting and installing SPDs.
