MLS type low-voltage switchgear is a low-voltage switchgear assembled by the factory using standard modules (FBA). It is suitable for power distribution systems with AC 50 (60) Hz, rated working voltage ≤ 690V, rated working current 5000A and below, and is used for energy distribution, conversion, control, and reactive power compensation.

　　Reasonable structure and high technical level. The rated current carrying capacity, breaking capacity, and dynamic and thermal stability performance indicators of MLS switchgear are higher than those of other types of low-voltage switchgear, and they are easy to maintain, safe, and reliable.

　　Good protective performance. The internal compartment can meet the requirements of GB7251 "form 4", and the highest protection level of the shell can reach IP55. It has passed the industry's highest 100kA internal arc fault test.

　　Interlocking is reliable. The anti misoperation interlocking is jointly completed by the circuit breaker handle operating mechanism and the drawer position mechanical interlocking operating mechanism. Its design is precise, highly logical, and can effectively prevent various possible misoperations. It can also be flexibly combined with the operation mode to achieve a complete mechanical interlocking scheme between cabinets.
