EPS 1P & 3P+N 40kA Voltage SPD — High-capacity surge protector suitable for single-phase or three-phase + neutral panels; up to ~40 kA discharge capability for robust surge suppression.
EPS 40kA Voltage Surge Protector / SPD — Great mid-range SPD with 40 kA surge rating for general panel protection.
EPS Imax 40kA Type 2 SPD (Model BY7 40) — Type-2 SPD commonly used in sub-distribution boards; good balance of cost and protection.
EPS 3P + N 40kA Voltage SPD — Three-phase + neutral SPD with 40 kA rating, ideal for three-phase industrial or commercial panels.
EPS Surge Protector 1P+N / 3P+N 20/40 /KA — Flexible model with both 20 kA and 40 kA ratings — good for basic surge protection needs.
EPS 1P + N 20/40 /KA Surge Protector — Single-phase SPD option for smaller residences or offices.
EPS 4P + N 20/40 /KA Surge Protector — Four-pole + neutral SPD for larger distribution boards or more complex three-phase systems.
RS PRO 1 Phase Industrial Surge Protector — (Bonus) Industrial surge protector from RS-brand, useful if you want alternate panel protection.
A Surge Protective Device (SPD) is installed in your electrical panel and acts like an “electric lightning shield.” It stops high-voltage spikes — often caused by lightning strikes, power grid switching, or large inductive loads — by quickly diverting the excess energy to earth/ground, protecting the panel and connected equipment (like TVs, computers, air conditioners, etc.) from damage.
Type-2 SPDs (like these EPS units) are widely used in sub-distribution boards in residential, commercial, and light industrial settings. They’re designed to react in nanoseconds and clamp transient over-voltages before they reach sensitive equipment.
Install the SPD downstream of your main distribution breaker, ideally as close as possible to the panel feed entry.
Ensure a good earth/ground connection — SPD effectiveness depends on solid grounding.
Always pair SPDs with proper protective devices like MCBs/RCCBs for complete circuit safety.
