2 ABB SACE -40 °C circuit-breakers | ABB Introduction ABB SACE Division goes beyond limits by launching a new version of circuit-breakers for extreme environments: a special version of breakers able to operate from -40°C to +70°C, which stand out on the market as being unique and complete. Over the past years, new industrial needs and rapid growth of renewable energy power generation have led to new require-ments for electrical installations in terms of extremely low operating temperatures. Sensitive to these market dynamics and closely following technological innovation, ABB SACE Division offers the new version of circuit-breakers suitable for applications where the ambient temperature is critical. Introducing a new generation of high performance grease and improving the reliability of the mechanical and electronic components at extremely low temperatures, ABB SACE LTT breakers are the best solution for: – Substations without heating in the coldest regions of the world – Wind turbine applications, both onshore and offshore – Industrial processes with outdoor switchboards – Dockyards and temporary external switchboards – Traction applications, such as external infrastructures
ABB | ABB SACE -40 °C circuit-breakers 3 ABB SACE Division now offers this distinctive temperature feature in its Emax air circuit-breakers and Emax switch-disconnectors. Moreover, a wide range of mechanical and electrical acces-sories completes the ABB SACE LTT version, making the offer complete and suitable for all customer requirements. The circuit-breakers and their accessories conform to the fol-lowing major International Standards: – IEC60947 – UL1066 This new special version can easily be recognized by the dedi-cated logo -40°C SACE LTT – Low temperature technology, which is always applied on the circuit-breakers.
4 ABB SACE -40 °C circuit-breakers | ABB Emax - Air circuit-breakers The ABB SACE Emax low temperature range covers all user needs with three sizes, rated uninterrupted currents up to 3200A according to IEC Standards and up to 3200A for breakers according to UL1066 Standards. It is available in three and four poles, fixed and withdrawable versions. Short-circuit performances, mechanical dimensions and fixing points of the SACE LTT version are the same as those for the standard version family. Moreover, the mechanical and electrical 1 accessories available for SACE LTT circuit-breaker are in common with the Emax standard version.
