Surge Protection Devices
Surge protective devices (SPDs) are designed to protect electrical and electronic equipment from damage caused by voltage spikes created by lightning strikes, switching transients, and inductive coupling. They are typically used in the following industrial applications:
- Protect power distribution equipment from high energy surges produced by utility switching, lightning, and other disturbances.
- Protect communications systems, such as serial lines and LAN cables, from surges that can disrupt operations
- Protect PLCs, HMIs, and sensors from surges that can cause malfunctions.
- Protect motor control systems, such as VFDs and starters, from surges that can damage motors and other components.
