Brief introduction about VA Dual Lamp Economy Edition Latching Relay Self resetting overvoltage and undervoltage protector:
When the voltage return to normal after 30 seconds the power supply automatically connects.
Product details:
Independent self resetting overvoltage protector, also known as self recovering overvoltage protector, adopts high-speed micro low power processor as the core, magnetic holding relay as the main circuit, and modular standard design. When overvoltage or undervoltage occurs in the power supply line, the protector can quickly and safely cut off the circuit under continuous high voltage impact, avoiding accidents caused by abnormal voltage entering the terminal electrical appliances. When the voltage returns to normal, the protector will automatically turn on the circuit within the specified time, ensuring that the terminal appliances operate normally without human supervision.
The self resetting overvoltage and undervoltage protector is suitable for users or loads with single-phase AC voltage of 220V, frequency of 50Hz, and rated working current of 60A and below. It is mainly used for the protection of residential sub box incoming lines or distribution lines that need to protect single-phase electrical equipment.
The characteristics of self resetting overvoltage and undervoltage protectors include:
Quick response: It can quickly cut off the power supply in the moment of abnormal voltage, reduce the damage of voltage to electrical equipment, and protect circuit safety.
Automatic recovery: When the voltage returns to normal, the protector will automatically connect to the power supply to ensure the normal operation of the electrical equipment, without the need for manual intervention.
Stable and reliable: With strong anti-interference ability, it can effectively prevent damage to electrical equipment caused by transient overvoltage such as lightning strikes and surges.
Easy to install: With a compact size and convenient installation, it can be widely used for circuit protection in residential, commercial buildings, industrial plants, and other places.
Long service life: Made of high-quality materials, it has high wear and corrosion resistance, long service life, and can effectively reduce maintenance costs.
