Product Description

LW30 switch has the advantages of small size, compact structure, exquisite material selection, good insulation, finger protection function, safety and reliability, you can add other contact blocks on the 3-pole standard block without removing the switch, the switch insulation distance is greater than other similar switches, fast disconnection speed, suitable for DC switch.

This series of switches adopts a composite structure of high-strength engineering plastics and high-quality alloy contact materials, and maximizes space utilization through three-dimensional contact layout. The core component adopts alloy double break contact system, with the patent design of fast breaking mechanism, effectively inhibit the arc generation. The products have passed ISO9001 quality management system certification and CCC and other international certifications. With its compact structure, excellent safety performance and flexible configuration scheme, this series of switches has become an important electrical component in intelligent buildings, industrial automation and new energy fields.

Working conditions of Lw30 Series Load Disconnect Change over Switch

Normal Working Conditions

(1) The ambient air temperature does not exceed +40 degrees, and the average temperature within 24 hours does not exceed 25°C;

(2) The lower limit of the ambient air temperature does not exceed -25°C
