not subject to shock or vibration.
If this is not possible, mount the circuit-breaker in a framework protecting it adequately.
For the dimensions to be considered for installation, see the chapter "6 - Installation" on page
24 where the following information can be found:
• minimum installation volumes of the circuit-breakers and derived versions
• distances to be respected for circuit breakers in a cell
• overall dimensions of the circuit breakers
• drilling of mounting holes
• drilling of the cell door
The mechanical and electrical characteristics are guaranteed between -25 ° C and +70 ° C.
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
• IEC60721-3-2 class 3C2
NOTE: the circuit-breaker is suitable for installation in environments with saline
concentrations no higher than 10 mg/m3.
penetration by dust is minimized.
If the environments are dusty (dust> 1mg/m3) it is required to always follow the second level
maintenance procedures.
Vibration The circuit-breaker is insensitive to mechanical or electromagnetic vibrations that meet the
following standards:
• IEC 60068-2-6 a) From 1 to 13Hz with movement equal to 1mm b) From 13 to 100Hz
with constant acceleration equal to 0.7g
• Naval specifications: RINA, BV, GL, ABS, LRs, DNV
