NORMAL SERVICE, MOUNTING AND TRANSPORT CONDITIONS
• storage and transport ambient temperature - 25°C + 55°C
• working ambient temperature - 20°C + 45°C
• in case of higher ambient temperature (ta) consider the following derating formula:
• relative humidity max 95%
• rated frequency 50-60Hz
• altitude max 2000 m a.s.l.
• pollution degree 3 according IEC 947-1
• can be mounted in any position
• mounting in enclosure:
in case of utilisation at full load and without adequate
ventilation, ensure a volume of about 5 times the volume
of the switch
• duty (IEC 947-1): 8 hours; uninterrupted; intermittent 60% class 30;
temporary; periodic
