Engineering Guide: Selecting the Right Surge Protection Device
When specifying SPDs for industrial boards, commercial complexes, or solar installations, correct coordination between protective stages ensures maximum equipment uptime and adherence to IEC 62305 protection zones (LPZ).
Type 1 (Class B) SPDs
Tested with a 10/350 μs impulse waveform. Installed at the service entrance or main incoming switchgear where direct lightning strikes or overhead line exposure occur.
Type 2 (Class C) SPDs
Tested with an 8/20 μs waveform. Positioned at sub-distribution boards to dissipate residual switching surges and indirect lightning transients before sensitive equipment.
Solar DC PV SPDs
Engineered for high DC open-circuit voltages (up to 1000V/1500V DC) with specialized Y-type varistor configurations to safely extinguish DC arcs during end-of-life disconnect.
