to shock or vibration.
If this is not possible, mount the circuit-breaker in a compartment protecting it adequately.
For the dimensions to be considered for installation, see the chapter "7 - Installation" on page 284 where the
references for following information can be found:
• minimum installation volumes of the circuit-breakers and derived versions in a cell
• overall dimensions of the circuit-breakers and the fixed parts
• drilling of mounting holes
• drilling of the cell door
The mechanical and electrical characteristics are guaranteed between -25 ° C and +70 ° C, -13 °F e +158 °F.
It was tested according to:
• IEC 60068-2-1: endurance at low temperatures
• IEC 60068-2-2: hot dry climate
• IEC 60068-2-30: hot humid climate
• IEC 60068-2-52 severity 2: saline mist atmosphere
• IEC 60947 (pollution level ≤ 3)
• IEC60721-3-6 class 6C3
• IEC60721-3-3 class 3C2
NOTE: the circuit-breaker is suitable for installation in environments with saline concentrations
no higher than 10 mg/m3.
