Feature:1. Widely used in various places where continuous power failure is not allowed.2. Designed for home rail-type installations and specifically for PZ30 distribution boxes.3. Automatic transfer switch suitable for emergency power system with AC power of 50 or 60 Hz and rated current of 400V, 60A.4. Compact structure, reliable transmission, convenient installation and maintenance, long service life.5. When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability and safety of the power supply.Specification:Item Type: Dual Power Automatic Transfer SwitchModel: W2R-100Rated Current Ie: 63AInsulation Voltage Ui: AC690V, 50HzRated Voltage Ue: AC400V, 50HzGrade: PC Grade: Can be connected and withstood, without breaking short-circuit currentUse Category: AC-33iBPole: 4PLife: Electrical: 2000 Times; Mechanical: 5000 timesShort Circuit Current At Rated Conditions: 50kASCPD (Fuse): RT16-00-63ARated Impulse Withstand Voltage: 8kVControl Circuit: Rated Control Voltage Us: AC220 V, 50HzCorrect Working Conditions: 85% Us-110% UsAuxiliary Circuit: 2 independent relays, each relay includes 2 sets of transformer contactsContact Capacity: AC220V 50HzTouch Time: <50msOperation Transition Time: <50msReturn Time: <50msOff Time: <50ms .Package List:1 x Switch1 x User ManualNote:For TSE was instantly excited. After the transfer is complete, the internal switch will damage the coils in the control circuit.The coil can work normally under 85% -110% of the rated operating voltage. Too low voltage in the coil may cause the coil to heat up and burn out.
