MVAIR Modular Switchgear
The MVAIR switchgear is a compact and modular switchgear lineup offering a wide array of configuration options. We have many standard and pre-designed configurations to choose from and specialize in creating custom solutions for challenging requirements. Our catalog and quick parts software make it easy for us to put together a proposal and drawing package for your project.
Standard configurations include both left, right, and rear cable incoming and outgoing sections. The switchgear has been designed to meet primary utility interconnection requirements and switchgear cell options include:
- Utility incoming cable compartment (left, right or rear bottom or top entry)

- Utility or customer metering compartment
- Cable or electrical bus outgoing compartment (left, right or rear bottom or top entry)
