Product Overview

LT1 voltage switch type series one-stage modular power supply surge protector based on！ EC and GB standard design. Applied to the first-stage protection of the power supply system, the product is a standard 35mm guide rail installation method.
The LT1 voltage switch series modular power supply surge protector has a high lightning current discharge capability, and the single module impact current can reach a maximum of 50 kA（10/350us）， which can prevent various electric surges including direct strikes.The first-stage power surge protection of the power supply system applied to the equipment system with high lightning strike risk can be combined for single-phase and three-phase substitution lines.

Product structure and performance characteristics

This product is an indoor fixed installation voltage switch type SPD, which is designed in accordance with current national standards such as GB/T18802.1； it has the advantages of large inrush current （limp：25KA） and low residual voltage （up：2.0KV） Its core components are composed of multi-level graphite gaps. Reasonable design and precise machining combine the spark gaps to form a sealed structure to ensure the safe distance inside the spark gap, even when surge current passes through, it will not produce There is no need to reserve space for arc leakage during installation. The quality is stable and reliable.
The product is installed at the junction of LPZOA or LPZOB and LPZ1， or at the main distribution box （cabinet） where the power is introduced, using 35mm standard guide rails. The connecting guide rail adopts 6-35mm2 multi-strand copper flexible wire.
The grounding wire should be a two-color wire of 16mm2 or more, and the length should not be greater than 500mm. In order to prevent the failure of the surge protector from affecting the normal operation of the power grid, the protector connected to the L line should be connected in series with a fuse or circuit breaker （note:select according to the nominal current In）。
