product manual

LMRD-series lightning arrester is a composite lightning arrester designed according to SPDI1 classification experiment requirements. It can be used for the first and second level protection of load equipment of power lines to prevent low voltage equipment from being over-voltage interference or even direct lightning damage. Lightning protection zone LPZOA-2 interface. The switch type composite lightning arrester is designed and manufactured according to GB 18802.1-2011, IEC61643-11.IEC61643-21 standard, has high lightning current discharge capability, and can be widely used in equipment system power supply with high lightning risk risk. Level lightning protection, can be combined for single-phase / three-phase power supply lines. LM Lehman Electric brand lightning protection certificate.

Features

This product is a one-port indoor fixed voltage switch type SPD, B+C level protection, single module inrush current up to 50KA (10/350uS), low residual voltage Up: 2.5KV, etc. Grade graphite gap composition. Reasonable design and precise machining combine the spark gaps to form a sealed structure to ensure the safety distance inside the spark gap. Even when the inrush current passes, no arc leakage will occur. It is not necessary to reserve leakage during installation. The space of the arc. Stable and reliable quality;

Standard 35mm rail mounting, compact structure, dual terminals (Kelvin mode);

The product is installed at the junction of LPZOA or LMPZOB and LPZ1 area, or at the main distribution box (cabinet) where the power supply is introduced;
