Vesta-AR: Medium Voltage Metal-Clad Arc-Resistant Switchgear

New Arc-Resistant, Compact Matal-Clad Switchgear: Meeting ANSI/UL Design Challenges

There is an unfilled market need for a medium voltage (5 kV – 15 kV), arc resistant, compact metal clad switchgear for a variety of applications such as data center, marine and critical health care facilities, etc. However, meeting the ANSI/IEEE/UL design challenges to come up with such compact, front accessible switchgear has been very difficult so far.

This white paper discusses the following topics:

• ANSI/IEEE Standards
• Design Challenges
• Analysis and Simulation Methods
• Testing Methods used by UL
