SYSTEMTRAB SYS N4
Surge Protective Device with Lightning Protection
The SYS N4 surge protective devices (SPD) are self-contained products designed to protect the main power service entrance from the damaging effects of a lightning strike. These devices are installed on the secondary side (low voltage side) of the distribution transformer that supplies the service entrance of a facility. To ensure effective operation, the SYS N4 device should be connected to the load side of the main service disconnect or to the load side of a protected circuit's disconnection device.
Due to its primary function as a lightning arrester, it is highly recommended to install the SYS N4 device at the main service entrance of a facility or electrical installation. The installation point must be where a neutral-to-ground bond exists, as required by the National Electrical Code (NEC) for service entrance power. This ensures proper functionality and adherence to safety standards.

Features & Benefits:
- Protects AC power mains from direct lightning strike energy.
- Combination lightning arrester and TVSS. Complete
coordinated hybrid over voltage protection system. - Discharges 50 kA of surge current as tested by the only lightning protection test standard - IEC 61024 (10/350 µs) waveform. Comparable to the energy of 500 kA (8/20 µs) waveform.
- Utilizes the revolutionary Arc Chopping Spark Gap
technology. Discharges complete lightning surge
currents while extinguishing up to 50 kA of follow
current. - Systems are flexible to meet any user requirement.
- Systems include 200 kA IC surge rated fusing with
disconnect. - ETL listed to UL 1449, 3rd edition.
