Part Number:Health Gearq8hwv45uxz Package Dimensions:15 x 10 x 8 cm Specification: Item Type: Dual Power Automatic Transfer Switch Model: ZGQ5-100/4P Material: Plastic Purpose: Switch to the backup power supply when the power fails, and switch to the main power supply when the power comes in Working Frequency: 50-60HZ Rated Current: 100A Rated Voltage: AC110-230V Working Voltage: AC220V Operation Mode: Automatic and manual ATS: CB level Conversion Time: 0.05 (S) Number of Poles: 4P How to Use: 1. Place the automatic transfer switch of the dual power supply on the debugging platform, and connect the corresponding power line according to the correct phase sequence. The phase line and the neutral line are connected in position, and the wrong connection is not allowed. 3. When debugging the three-pole switch, the common and spare neutral wires should be connected to the neutral terminal (NN and RN) respectively. 3. Set the dual power supply automatic transfer switch to work in the self-turning and self-resetting mode. If the voltage of the two power supplies is normal, the switch should be placed in the common power supply position, and the common power supply is closed. 4. Set the common power supply NA, NB, NC, NN for any phase loss, the dual power supply should be automatically converted to the backup power supply, if the common power supply returns to normal, it should be converted back to the common power supply 5. Adjust the voltage of any phase of the common power supply to the predetermined undervoltage voltage value, and the dual power supply should automatically switch to the standby power supply. When the normal power supply returns to normal, the switch should return to the normal power supply PackageList: 1 x Dual Power Automatic Transfer Switch 1 x User Manual [Practical Auto Switch]: This is a pretty practical Dual Power Transfer Switch Circuit Breaker, it is designed for shifting normal power to backup power, it adopts quality high sensitivity chip and silver contacts that can greatly improve the conductivity and allows it to have quick response, when the regular power supply fails, the backup power supply will work immediately to ensure the continuity, reliability and safety of the power supply [Safe and Reliable]: This Automatic Transfer Switch is reliable, not only can it ensure the continuity, reliability and safety of the power supply, but also it is durable and safe, it is made of quality thick plastic material, which has high hardness and strength, hard to break or damage, and it is flame retardant, good insulation, high temperature resistance, anti aging,durable and reliable to be used for a long life [Simple Installation and Usage]: It is quite simple and convenient to use this Quick Response Circuit Breaker Changeover Switch, it is designed with built in regular standby opening signal output port, which can be connected with signal indicator light, which is convenient for observation outside the cabinet, and it features compact size that is convenient for installation [Wide Application]: This is a great practical Dual Power Transfer Switch Circuit Breaker, can help quickly change power supply and ensure continuity and safety of the power supply, simple and convenient to use, and features reliable quality, can be widely used for switching to the backup power supply when the power is cut off, and switching to the main power supply when the power comes in [Satisfactory Guarantee]: We are a customer oriented company that is dedicate to provide best product and fast service, if you have any problems with this product you can free to contact us and we will help solve the problem for you as soon as possible See more product details [Practical Auto Switch]: This is a pretty practical Dual Power Transfer Switch Circuit Breaker, it is designed for shifting normal power to backup power, it adopts quality high sensitivity chip and silver contacts that can greatly improve the conductivity and allows it to have quick response, when the regular power supply fails, the backup power supply will work immediately to ensure the continuity, reliability and safety of the power supply [Safe and Reliable]: This Automatic Transfer Switch is reliable, not only can it ensure the continuity, reliability and safety of the power supply, but also it is durable and safe, it is made of quality thick plastic material, which has high hardness and strength, hard to break or damage, and it is flame retardant, good insulation, high temperature resistance, anti aging,durable and reliable to be used for a long life [Simple Installation and Usage]: It is quite simple and convenient to use this Quick Response Circuit Breaker Changeover Switch, it is designed with built in regular standby opening signal output port, which can be connected with signal indicator light, which is conveni
