General
YCS6-D series Surge Protection Device is suitable forTT,IT,TN-S,TN-C and TN-C-S,the power supply system with the rated voltage up to 230/400V and AC 50/60Hz.Itsdesign corresponds to IEC61643-1.The product is usually installed in the incomingline low voltage distribution box of the building,and it can release 20kA lightningstroke current.

General
1. YCCH6/YCCH7 series AC contactor (hereinafter referred to as the household appliances control a contactor) is used for remote switch on and off without a sense of feeling or low load, resistance furnace, household appliances and similar low load, motor and other household.
2. The main contactor is used in AC 50Hz/60Hz, rated voltage to 400V, rated current of power system to 100A, AC-1, AC-7a (in no sense or sense of low load, resistance furnace, household appliances and similar low load) categories, long distance switch and control circuit.
3. Contactor is not used for breaking short circuit current, so it is necessary to choose suitable short circuit protection electrical equipment.

Products Overview
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
