Eaton’s New E2VAC Mining Vacuum Circuit Breaker Helps Enhance Safety and Equipment Protection in Mining and Metals Applications

Date: May 27, 2015

PITTSBURGH … Power management company Eaton today announced the new E2VAC Mining Circuit Breaker, a low-voltage, vacuum-based breaker solution with advanced monitoring and optional integral remote racking. Designed to improve reliability, productivity and worker safety in powercenters and other panel applications in underground mining and metals operations, the E2VAC’s vacuum contactor technology significantly reduces the risk of energy released during an arc event.

The new 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.

“Safety is paramount in mining operations, and this addition to Eaton’s Mining Molded Case Circuit Breaker series reflects Eaton’s innovative approach to helping protect people and equipment,” said Andy Smith, product manager, Eaton. “The E2VAC will not only improve mine safety with integral remote racking and vacuum interruption, but also with better monitoring – reading kilowatt demand, reactive power demand, power factor and frequency measurements, to name a few.”

Additionally, the E2VAC includes audible and visual blown fuse indications, eliminating the reliance on electronic notifications to personnel and allowing users to look directly into the breaker for a blown fuse signal, enabling efficient and safe repair or replacement.

Eaton vacuum contactors used in conjunction with power fuses facilitate the E2VAC’s high interruption rating of 100,000 Amps.
