- The ABB SACE Emax series of low voltage air circuit breakers has a heritage dating back to 1942, with the original Emax series launched in 1996. The 'New Emax' series was introduced in 2003, and the Emax 2 in 2013. The Emax 3 was globally premiered in July 2025 and officially launched in Malaysia in January 2026.
- The Emax E (specifically Emax /E or Emax 2/E) is a specialized version within the broader Emax and Emax 2 ranges, designed for demanding applications with service voltages exceeding 690V AC, up to 1150V AC for the Emax/E and up to 1380V AC for the Emax 2/E.
- The Emax E is specifically engineered for high-voltage AC applications (over 690V AC), offering high performance in a compact size, which can reduce switchboard dimensions by up to 30%. It also provides advanced protection, measurement, and connectivity features, making it suitable for demanding environments like mines, oil and chemical plants, traction, and renewable energy installations.
