Arc Resistant Medium Voltage MCC
Overview
Powell combines the latest vacuum contactor design and starter components with the maximum voltage, current, and interrupting rating with our arc resistant construction technology. This provides a unique opportunity to further enhance the safety of your facility and give you the maximum in protection for operators and personnel.

Our medium voltage arc resistant MCC design was completed with the end user in mind. It is designed to match our PowlVac ® metal-clad switchgear. Adding a main circuit breaker or a main-tie-main arrangement does not require an additional transition section. In addition, our designs offer the following capabilities: - Front and Rear accessible
- Fixed-mounted isolated switch and starter
- FVR
- FVNR
- Multi-speed
- Reduced voltage or soft starter capability

Main circuit breakers are designed to match and line with our PowlVac® metal-clad switchgear. Adding them or main-tie-main arrangements does not require any transition sections.

Arc resistant medium voltage motor control is regularly close coupled to medium voltage metal-clad switchgear. Designing the assembly as one integral unit reduces the amount of coordination required between assemblies, saving time and money. An example of this would be a main-tie-main circuit breaker assembly for dual motor control lineups where multiple sources are involved.
