Overview
Features & Benefits
VESTA-AR™ Medium Voltage Metal-Clad Arc-Resistant Switchgear with magnetically actuated VM1 circuit breaker technology is designed to meet the needs of customers who demand the highest quality power distribution assembly with the smallest footprint (24” x 96” x 60”).
Vesta’s plenum design redirects dangerous arc flash energy away from operating personnel, front-facing current transformers simplify maintenance, and magnetically actuated breakers operate up to 100K times, greatly reducing the need of service, In all, over a dozen key features were built into this revolutionary
- Rated Voltage: 5-15kV; 95kV BIL
- Current: 600-2000A; 31.5kA, 40kA, 50kA
- Dimensions / 1200A: 24” x 96” x 60”
- Dimensions / 2000A: 30” x 96” x 72”
- Magnetically actuated breaker – up to 100,000 operations
- Full front accessibility
- Draw out breaker, PT, CT & CPT
- Shortest breaker pole spacing between phases
- Front and rear viewing windows
- Epoxy insulated bus bar as standard
- Plenum design incorporated into structural configuration. No additional height requirement.
- UL & cUL listed; Type 2A and 2B in accordance with ANSI/IEEE standards
Front Accessibility
Full front accessibility for cable connections and current transformers (CT); this design feature ensures ease of maintenance, minimal usage of floor space and creates a safe environment.
Front & Rear Viewing Windows
Located on the front and rear of the assembly, these viewing casements allow complete access to viewing of the bus bar compartment for maintenance to assess any signs of overheating of the bus.
Insulated Bus Bar System
Medium Voltage insulating and support system with specialty designed structure for current transformers (CT’s). Epoxy insulated bus as standard.
Testing
KEMA-Powertest completed. Rigorous testing shows fully reinforced and sealed joints, hinges and latches, which reduce the risk of damage to maintenance personnel and other existing equipment in the event of an arc flash.
