4-pole AC surge protection device for three-phase installations against lightning and power surges.
SKU: 3pole spd 20ka-40ka
Description
The 4-Pole AC SPD provides surge protection across all three phases and neutral in a three-phase electrical installation. Lightning strikes, switching transients, and grid disturbances can send destructive voltage spikes through the mains supply, damaging expensive equipment like motors, PLCs, computer networks, and medical devices. This SPD diverts those surges safely to earth, keeping downstream equipment safe. Each pole module features a visual status indicator so you can confirm protection is active at a glance. DIN-rail mountable for clean installation in three-phase distribution boards alongside your MCBs and RCDs.
