Courtesy: EatoEaton’s E2VAC Mining Circuit Breaker is a low-voltage, vacuum-based breaker solution with advanced monitoring and optional integral remote racking. It is designed to improve reliability, productivity, and worker safety in power centers and other panel applications in underground mining and metals operations. The E2VAC’s vacuum contactor technology is also designed to significantly reduce the risk of energy released during an arc event. The breaker is available as a fixed drawer assembly or with integral remote racking capability that allows the breaker to be racked in and out from service at a safe distance. The breaker also features the EDR-5000 relay with advanced monitoring capabilities, which improve on basic monitoring tools to help maximize power quality.

By improving diagnostic and communications options, the breaker is designed to indicate symptoms before failure occurs, expanding safety and reliability for workers and the surrounding equipment. The E2VAC includes audible and visual blown fuse indications, which is designed to eliminate the reliance on electronic notifications to personnel. It also allowsusers to look directly into the breaker for a blown fuse signal. Eaton vacuum contactors used in conjunction with power fuses facilitate the E2VAC’s high interruption rating of 100,000 Amps.
