— Installation environment
Environmental conditions The devices can be installed in industrial environ- ments with pollution level 3, IEC60947. SACE Emax 2 circuit breakers also comply with:
Altitude SACE Emax 2 air circuit breakers do not change in rated performance up to 6600 feet. However, above 6600 feet, the properties of the atmosphere in terms of composition, dielectric capacitance, cool- ing power and pressure can vary and, therefore, the performance of the circuit breakers is subject to derating, which is capable of measurement by means of the variation in maximum rated service voltage and rated uninterrupted current.

Vibration The circuit breakers have been tested according to: • IEC60068-2-6 • From 1 to 13 Hz with amplitude 1mm • From 13 to 100 Hz with constant acceleration 0.7g
Electromagnetic compatibility The use of certain devices in industrial installations may cause electromagnetic interference in the elec- trical system. SACE Emax 2 circuit breakers have been developed and tested for electromagnetic compatibility in accordance with IEC 60947-2; Appendices J and F, ANSI C37.90.1 and C37.90.2.
