Product information

Description

Noark Ex9UE2 20 4P 275 is a 4-pole surge arrester designed for installation in distribution boards to protect electrical installations and connected equipment from transient overvoltages and lightning-induced surges. Rated for a nominal system voltage of 275 V, this device limits peak voltage and diverts surge currents to reduce the risk of equipment damage and insulation breakdown in residential, commercial and light industrial power systems.

Advantages

The 4-pole design provides coordinated protection across all conductors, ensuring balanced suppression of common-mode and differential-mode surges. Compact DIN-rail mounting allows integration into standard consumer units and distribution panels. The device is built to activate quickly during transient events and to conduct surge currents safely away from protected circuits, minimizing downtime and maintenance needs.

Suitable for

  • Residential main distribution boards and sub-distribution panels
  • Commercial premises such as offices, shops and small restaurants
  • Light industrial installations and machinery control panels
  • Protection of sensitive electronic equipment like routers, servers and HVAC controls

Key specifications

  • Number of poles: 4-pole protection covering all conductors
  • Nominal system voltage: 275 V
  • Mounting type: DIN-rail mounting for distribution boards
  • Function: Limits peak transient voltage and diverts surge currents
  • Application environment: Residential, commercial and light industrial power systems

How to use

Install the surge arrester in the distribution board on a standard DIN-rail according to local electrical regulations. Connect the device so that all live conductors and the neutral (where applicable) pass through the arrester terminals to ensure full 4-pole protection. Ensure correct coordination with upstream and downstream protective devices and verify earthing is in place to provide a low-impedance return path for diverted surge currents. After installation, test and document the protective arrangement and perform periodic inspections as part of routine electrical maintenance.

Usage recommendations

Select surge protection devices that match the system voltage and expected exposure to transient events. Combine the arrester with proper earthing and overcurrent protection to achieve effective and safe surge mitigation. Replace or professionally inspect the device after a significant surge event or if indicator signals (if present) show end-of-life status.
