Eaton E2 Mining Service Breakers
E2 Mining Service Breakers
Product Overview
State-of-the-art E2 mining service breakers incorporate the rigid specifications and testing procedures developed by a focus group led by engineers from several large coal companies and Eaton design engineers. Additionally, the performance of these breakers was proven and verified during hundreds of hours of field testing in harsh mine environments.
E2 mining breakers are available in 600 Vac and l000Y/ 577 Vac. Interchangeable trip units can be used on either 600 or 1000 Vac frames.
To upgrade from Classic to the current offering of E2 mining circuit breakers, consult the cross reference information HERE.
The E2 mining breaker family is designed especially for trailing cable application per MSHA 30 CFR 75. Field interchangeable electronic rms sensing trip units are available from 150 to 2000 amperes with instantaneous pickup settings conforming to the code of Federal Regulations 30 CFR 75.601-2. Electromechanical trip units are also available with a wide range of magnetic pickup ranges
E2 electronic trip units are the first to provide the mining industry with true rms sensing, made possible by the custom ASIC microprocessor in each electronic trip unit.
E2 breakers are designed to be physically and electrically interchangeable with Classic Mining Service Breakers and supersede Series C® Mining Service Breakers. The table to the below outlines direct replacements.
