For applications up to 1150V AC
Over the past years, there has been an increasing requirement for high service voltage in industrial plants. ABB has always been focusing on high demanding applications, so that customers could find a reliable solution for any application need.
Emax circuit-breakers and switch disconnectors can be supplied in a special version for rated service voltages up to 1150 V in AC. Typical applications are installations in mines, oil and chemical plants and traction.
Emax/E version is derived from the corresponding standard Emax, thus maintaining same flexibility of installation, fixed and withdrawable, and same range of accessories. In order to guarantee maximum reliability, tests on circuit breakers and switch disconnectors have been performed at 1250V AC.
