75A 7 Position LW31 series Rotary Changeover Switch Cam Switch 4 Sections

Description:

LW31 series Rotary Changeover Switches applied to Complete electrical switchgear and Three-phase asynchronous motor load start shift steering; For using as main circuit and auxiliary circuit conversion. It’s a good substitution for other cam switches

General Features:

1. Wide range of function for switching, it has 20A,25A,32A,50A,75A
2. Capability for switching of resistive, or inductive, or mixed loads.
3. The most economical way for switching electrical loads.
4. Made of the best materials with high mechanical, electrical and thermal resistance.
5. Double-break bimetallic contacts made of silver alloy and Copper.
6. Terminals with screws provided with cable clamp.

Advantage:

1. LW31 series Rotary Changeover Switches have the characteristics of small size, multi-function, compact structure, exquisite material selection, good insulation, flexible conversion operation, safety and reliability, and novel appearance.
2. LW31 series Rotary Changeover Switches have many different types of operation handle to choose by customer(“R”,”I” types)
