Advanced Soft Starter Cabinet 220V-660V 22kw-350kw

In the mining scenario, the start-up process of three-phase motors (17kw-320kw) such as crushers and ball mills often encounters two major challenges: Firstly, the traditional start-up scheme's inrush current of 4 to 8 times leads to excessive grid voltage drop, frequently triggering tripping and affecting mining efficiency; Secondly, mechanical shock during heavy-load startup can easily cause wear of gearboxes and damage to bearings, resulting in persistently high equipment maintenance costs. This 220V-660V, 22kw-350kw soft start cabinet is precisely tailored as a solution for the mining industry. ​ As a complete control system integrating a soft starter, bypass contactor and protection unit, it first strictly controls the starting current within ≤3 times the rated current (Ie) through "impulse suppression" technology, and stabilizes the grid voltage drop within 5%, completely avoiding grid fluctuations caused by starting impulse and ensuring the stability of the overall power supply…
