Product introduction

YCZF7 self-recovery over-and under-voltage protector is suitable for users or loads with AC voltage of 230V/400V, frequency of 50Hz and rated working current of 100A or less. Mainly used in residential household boxes or other distribution lines that need protection.
YCZF7 self-recovering over-and-under-voltage protector is a new type of intelligent protection electrical appliance. The product adopts modular standard design. When the power supply line has over-voltage or under-voltage, the protector can quickly and safely cut off the circuit to avoid the accident caused by abnormal voltage entering the terminal electrical appliance. When the voltage returns to normal value, the protector will automatically switch on the circuit within the specified time to ensure the normal operation of the terminal electrical appliance under unattended conditions.
