1ATSE consists of TSE and controller, widely used in various places that do not allow continuous power failure. 2This product is designed for home rail type installation and is specially used for PZ30 distribution box. 3Automatic transfer switch suitable for emergency power system with AC power of 50 or 60 Hz and rated current of 400V, 60A. 4When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability and safety of the power supply. 5Compact structure, reliable transmission, convenient installation and maintenance, long service life.Model: W2R-100 Rated Current Ie: 100A Insulation Voltage Ui: AC690V, 50Hz Rated Voltage Ue: AC400V, 50Hz Grade: PC Grade: Can be connected and withstood, without breaking short-circuit current Use Category: AC-31B Pole: 4P Life: Electrical: 2000 Times; Mechanical: 5000 times Rated Condition Short Circuit Current: 50kA SCPD (Fuse): RT16-00-63A Rated Impulse Withstand Voltage: 8kV Control Circuit: Rated Control Voltage Us: AC220 V, 50Hz Correct Working Conditions: 85% Us-110% Us Auxiliary Circuit: 2 independent relays, each relay includes 2 sets of transformer contacts Contact Capacity: AC220V 50Hz Touch Time: 1 x Switch1 x User ManualFor 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.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
