A2Z-MES Series Metal Enclosed Modular Switchgear is designed for medium voltage applications where compact structure, reliable switching performance, easy maintenance, and safe operation are required.
The series can be manufactured up to 40.5 kV rated voltage, 1250 A rated current, and 25 kA short-circuit withstand level. Its compact metal enclosed modular structure makes it suitable for power generation, transformer substations, renewable energy, industrial facilities, transportation, mining, and utility applications.
A2Z-MES Series is designed in accordance with IEC 62271-200 and related international medium voltage switchgear standards. The product family includes fixed truck circuit breaker and withdrawable truck circuit breaker configurations according to project requirements.
The switchgear structure is based on a compact modular design with independent accessible compartments, mechanical and electrical interlocking systems, internal arc safety design, and optional special configurations for harsh environmental conditions.
