Ambient temperature
3VA UL molded case circuit breakers may be used at ambient temperatures from -25 °C to +70 °C.
3VA UL thermal-magnetic circuit breakers are calibrated for use at +40 °C. There may be reductions in the rated operational current depending on ambient conditions, frame size and accessories used (See Derating table below).
Please contact Siemens concerning operating conditions that are outside the values specified in the derating table.
The permissible storage temperature in original Siemens packaging is between -40 °C and +80 °C.
