Description YC9VA voltage and current display relay is a microprocessor-based voltage monitoring device for single-phase AC networks to protect electrical equipment from surge voltage. The device analyzes the main voltage and displays its current value on a digital indicator. Load is switched by electromagnetic relay. The user can set the current voltage value and delay time through the button. The value is stored in non-volatile...

General YCB7RL-100  series  electromagnetic  residual  current  operated  circuit  breaker  is  mainly suitable for AC distribution networks with a rated working voltage of 230V or 400V at 50Hz  and a rated current of 63A.Used for indirect contact protection of people,and can also be used  to  prevent  fire   hazards  caused   by  insulation  damage  to  circuits  and  equipment,  resulting in ground fault currents. Feature Protection against the effects of sinusoidal alternating earth fault...
