Wiring Diagram & Installation

The AC Type 1 Surge Protective Device (SPD) is designed to handle a 10/350 µs lightning current waveform, protecting electrical systems from direct lightning strikes and high-energy surges.

It is typically installed at the main circuit breaker of the load center, such as the main distribution board, to provide primary surge protection and safeguard sensitive equipment.
