RMU
ASRMU Series – Medium Voltage Modular Switchgears (12 kV / 24 kV / 36 kV)
Astor Enerji’s ASRMU series medium voltage modular switchgears are designed to meet high standards of safety, durability, and performance. Optimized for various voltage levels, these switchgears offer safe, long-lasting, and efficient solutions for power distribution centers, industrial plants, renewable energy power plants, and infrastructure projects.
The ASRMU series ensures uninterrupted energy flow even under demanding operational conditions, thanks to its production in compliance with IEC standards, high insulation strength, and short-circuit performance. Each model features superior insulation and switching characteristics tailored to its specific area of application.
ASRMU series switchgears provide safe operation at various voltage levels from 12 kV up to 36 kV.
- Operational safety is at the highest level due to high insulation strength and internal arc protection features.
- With a rated current capacity of 630 A, it provides a stable energy flow in medium voltage systems.
- Ideal for high-performance switchgear systems with short-circuit withstand capacity up to 25 kA (ASRMU 12).
- Its modular structure offers easy installation and maintenance advantages, designed to be compatible with system expansions.
