What is the difference between RMU and metal-clad switchgear?

An RMU is compact and modular for secondary distribution and loop networks. Metal-clad switchgear such as KYN28 is larger and used for primary distribution, higher feeder current and more complex protection schemes.

How do I specify an RMU module combination?

Please provide the required incoming, outgoing, transformer protection and metering functions. Common combinations include C, F, V and M modules, depending on the system design.

Can RMU be used in a prefabricated substation?

Yes. RMU is commonly integrated into compact substations as the medium-voltage section for incoming and transformer protection.

What should be checked for automation?

Motor operation, auxiliary contacts, RTU interface, power supply, CT/PT configuration and communication protocol should be confirmed if distribution automation is required.

Can you provide SF6-free options?

SF6-free requirements should be discussed during engineering review. We can support project evaluation and recommend suitable switching technology based on voltage, current and local regulation.
