CHINT NH40 manual changeover switch

This is a CHINT NH40 manual changeover switch. Key features include:
Used for infrequent manual switching on and off the circuit and isolating the power supply in industrial distribution equipment.
It allows for safe switching between the main power supply and a generator without connecting both sources simultaneously.
The switch typically has an “on” position for each power source and an “off” or neutral position where neither source is connected.
It is a 4-pole rotary handle design.
Suitable for applications requiring reliable dual power transfer and emergency power backup.
