Requirement for safety measures in place against electric shocks, applying to electric devices. Protection category I: Protective earthing Protection category II: Protective insulation Protection category III: Protective extra-low voltage
IP = Ingress Protection. Indicates the level of protection for the housing against external influences, in compliance with DIN EN 60529. The first figure describes protection against foreign bodies, the second figure describes protection against water. The higher the individual values are, the higher the respective protection level is.
Primary nominal voltage
maximum ambient temperature
Describes the maximum temperature that should not be exceeded, so that device life expectancy is not negatively influenced, and functioning continues optimally for as long as possible.
minimum ambient temperature
Describes the minimum temperature required, so that device life expectancy is not negatively influenced, and functioning continues optimally for as long as possible.
