[Copy] YCH7-125 AC Fuse Isolation switch for air conditioner

Product Detail

YCH9-125 series isolating switch is suitable in the resistive circuit of AC 50/60HZ, rated voltage 230/400V, rated current up to 125A.

It's used primarily for circuit's turning on or off in non-load ed situation. And it functions on connection and isolation between lines

and power, especially suitable to isolate power effectively and prevent circuit breaker from closing accidentally when maintain the

circuit in order to ensure the safe operation of maintainer.

Product standard: IEC600947-3

Contact position indication

Anti-skid handle for easy and reliable operation

Flame retardant,high temperature resistance and impact resistance
