Over and Under Voltage Protector
IQG 63 type 3P+N
Scope applicationThe multifunctional overvoltage, undervoltage, and overcurrent intelligent protector is a comprehensive intelligent protector that integrates overvoltage protection, undervoltage protection, and overcurrent protection. When any line experiences overvoltage, undervoltage, or overcurrent faults, this product can instantly cut off the power supply to avoid unnecessary damage to electrical equipment.When the line returns to normal, the protector…
product overview
The iQG self recovering overvoltage and undervoltage protector is a new type of intelligent protective electrical device. The product adopts an modular standard design. When the power supply line experiences overvoltage or undervoltage, 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 device. When the voltage returns to normal, the protector will automatically connect the circuit within the specified time, ensuring that the terminal electrical device operates normally without human supervision. The iQG self recovering overvoltage and undervoltage protector is suitable for users or loads with AC voltage of 230V/400V, frequency of 50Hz, and rated working current of 80A or below, and is used in residential distribution boxes.
Main function: Overvoltage and undervoltage protection function
Compliant with standards: JB/T 12762

Installation and wiring
Before installation, check whether the product logo matches the conditions used
Connect the incoming and outgoing terminals correctly according to the product identification (the load current should not exceed the rated current value of the product)
The N pole must not be connected incorrectly and must be reliably wired, otherwise the protector cannot function properly
other
When the protector is powered on for the first time, it needs to delay for 30s+10s before supplying normal power to the load. The protector’s N line is zero and L is the live line, and cannot be connected incorrectly
The wiring method is: upper wire and lower wire or lower wire. Before use, please tighten the wire clamp screw to prevent poor contact and damage to the product
LED indicator: green light always on – normal red light always on – protection
Overvoltage and undervoltage must be connected to zero, and the protector provides protection when the line is disconnected from zero or any phase of the live wire is disconnected
After overvoltage or undervoltage of 3P+N products, the three-phase neutral line can only resume normal operation when it is at the recovery value
