Max. Voltage Rating 600 V AC Degree of Protection IEC: IP20, UL/CSA Type: - Characteristics These tripping characteristics are mean values of the spreads at 20 °C ambient air temperature in a cold state. Tripping time depends on response current. When the devices are at operational temperature the tripping time of the overload relay falls to approx. 25 % of the read oﬀ value.
