AC contactor breakthrough! Epoch-making invention of low-voltage electrical appliances! New Generation - Magnetic Starter NC no spark! 

 The traditional magnetic starter for the exchange of contacts for the main body, connected to the AC contactor is random and disconnected, so the majority of contactor contacts is carried out with the current conditions on and off, which making contacts in the on and off very often accompanied by loss of electric arc phenomena, which not only caused great environmental electromagnetic pollution, but also on the AC contactor contacts itself against a larger , thereby greatly reducing the service life of AC contactor, AC contactor making various types of machinery as wearing parts, greatly improving the user's cost. 

 This product is controlled by microcomputer electromagnetic relay switch in the on-off does not produce sparks, which can not only greatly extend the life of the contacts, while the same can be greatly reduced AC contactor rated current specification manufacturing costs, and to the same specifications of the product volume are compressed to a minimum! 



 Use 

 It applies to all kinds of air compressors, auto water pumps, fans, three-phase squirrel-cage motor, and so the direct start, stop, automatic control, phase failure, overload protection purposes. 



 Work 

 The machine uses new patented technology, the use of precise micro-computer control, making the master or the electromagnetic relay in the closing minutes when the gate does not produce any sparks, thereby greatly extending the life of the electromagnetic relay, completely solved work with frequent exchanges and contacts, the excessive damage to, and integration of electronic phase failure and overload, stall protection function may prevent the motor overload due to broken phase and, burning a motor stall occurs. 





 Features: 



 1, long service life. Unlimited number of starts, the actual test a million times. 

 2 ultra-small size is easy to install. 

 3, closing or sub-gate does not produce sparks, greatly reducing the electromagnetic interference and noise pollution. 

 4, round motor protection, built-in electronic phase failure, overload and locked rotor protection, protection of sensitive characteristics of precision, 

 Fault LED lights indicate at a glance. 



 Main technical parameters 



 1, for the supply voltage 380V, 50Hz power frequency for low-voltage three-phase three-phase AC power off the motor frequently start control. 

 2, set the open phase protection time is less than 3-4 seconds. Overload delay action time 15-30 seconds. Stall protection delay action time of 5 seconds. 

 3, load capacity: 380V 18A, 7.5KW directly drive the following three-phase AC motor. 

 4, set the setting current: 2A-22A 

 Matching requirements in accordance with factory factory factory default by the current specifications of any of the following 22A.
