Surge Protection Device (SPD)

A Surge Protection Device (SPD) is a critical component for protecting sensitive electronic equipment from transient overvoltages or surges. Unlike lightning arresters which handle massive external surges, SPDs are designed to protect against internal surges caused by switching operations, as well as residual external surges. They are essential for safeguarding PLCs, VFDs, computers, and other microprocessor-based devices.

Key Features

• Provides fine-level protection for sensitive electronic components.
• Available in different types (Type 1, 2, 3) for coordinated protection.
• Compact, modular design for easy installation in panels.
• Visual end-of-life indicators for timely replacement.
