Spec:Item Type: Power Automatic Transfer SwitchProduct Model: NLQ4-125/4PSwitch Type: Secondary power distributionRated Current: 100ARated Voltage: 400V ACInsulation Voltage: 690V ACRated Frequency: 50Hz/60HzElectrical Grade: PC grade isolation typeService Life: Electrical: 2000 Times; Mechanical: 5000 TimesRated Short Circuit Current: 50kASCPD (): RT16-00-63ARated Impulse Withstand Voltage: 8kVControl Circuit: Rated Control Voltage Us: AC220 V 50HzNormal Working Condition: 85% Us-110% UsAuxiliary Circuit: 2 Independent relays, each relay includes 2 sets of transformer contacts Capacity: AC220V 50HzTouch Time: Transition Time: Return Time: Off Time:packing list:1 x Power Automatic Transfer SwitchNote:1. The maximum ambient temperature should not exceed 40℃, the minimum should not be lower than ‑5℃, and the average temperature within 24 hours should not be higher than 35℃.2. The altitude of the installation site should not be higher than 2000meter.3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature of ‑5℃, the relative humidity is higher, for example, if the temperature is 25℃, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes.4. During conversion, the internal switch will lose the coil in the control circuit. The coil can work normally at 85%‑110% of the rated working voltage. If the voltage in the coil is too low, it may cause the coil to heat up or burn out.

• SILVER CONTACTS IMPROVE CONDUCTIVITY: The use of silver contacts in this product can greatly improve the conductivity and service life of the product
• CONVENIENT OBSERVATION: Built in timing standby open output port, which can be connected to a indicator light, convenient for observation outside the cabinet, rail type installation design
• FLAME RETARDANT MATERIALS: Made of good quality flame retardant plastic materials, possess good insulation, high temperature aging and
• MILLISECONDS SWITCHING WITHOUT INTERRUPTION: When the normal power supply is abnormal, the backup power supply works immediately, and the power supply is switched in milliseconds without interruption, which ensures the continuity, reliability and safety of the power supply
• FOR VARIOUS PLACES: Switch to the backup power supply when there is failure, and switch to the main power supply when power recovery. Widely used in various places where continuous power failure is not allowed, like factories, shopping malls, nurseries, etc.
