Eaton’s E2VAC circuit breaker enhances safety in mining



August 25, 2015 – Eaton says its new E2VAC mining circuit breaker is 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 reduces 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 monitoring capabilities. 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.
 
Additionally, the E2VAC includes audible and visual blown fuse indications.
