Hager SPN440D Surge Protector 4P 40mA

Hager SPN440D Surge Protector | 4P 40kA (Type 2)

Protect three-phase electrical installations and sensitive equipment with the Hager SPN440D Surge Protector. This device is a 4-Pole (4P) Type 2 surge protection device (SPD). It has a high discharge capacity to safeguard against damaging voltage surges. These surges are often caused by lightning strikes or electrical switching. 

Key Features & Benefits:

• 4-Pole Protection for Three-Phase Systems. Coordinated surge protection for all live conductors and the neutral, essential for three-phase supplies.
• High 40kA Surge Discharge Capacity. The device offers a high 40kA per phase discharge capacity & effectively diverts powerful transient overvoltages safely to earth.
• As a Type 2 device, it is designed for installation at the distribution board level. 
• Visual Status Indication & Thermal Protection. It features a clear window with a colour-coded status indicator. 
• Provides the main barrier against typical induced surges.
