Features:
High Surge Energy capacity protects downstream loads from voltage spikes and line transients.
Connected in parallel and use an MOV to clamp high-voltage surges.
Thermal protection circuit disconnects load under high energy absorption events.
This device is primarily used in the main electrical panel for the protection of 1-phase systems.
Fail safe/self-protection design.
Visual red-green indicator alerts when surge module needs replacement.
Certified: IEC61643-11:2013, Class II.
Remote alarm contact.
Touch Safe, IP20 Degree of Protection
Surge module plugs into DIN Rail mount base assembly for easy replacement in field.
Double thermal disconnection device, provide more reliable protection.
Two pole device provides full protection.
High discharge current — Imax 60kA per pole.
Narrow size, special design for saving installation space — width 18mm/pole, single phase.
Application:
Useful in case of high lightning density areas.
This surge arrestor is suitable for all installations where risk of surge and spike activity and, particularly due to nearby lightning activity, as in telecom installations, oil rigs, and open exposed areas with metal structures.
This unit should be installed in all building and sites at high risk (where a Lightning Protection System is in place and there is risk to human life such as schools, hospitals etc.).
