 Technical Information
Series L9 UL489 Miniature Circuit Breakers

Applying L9 UL489 Miniature Circuit Breakers in accordance with UL & NEC Guidelines
The L9 circuit breakers are rated in RMS amperes at a 40 °C (104 °F) ambient temperature per UL 489/CSA C22.2 No. 5. This temperature is used as the
ambient temperature external to an industrial enclosure. If a circuit breaker is applied in a temperature that exceeds the 40 °C (104 °F) ambient rating, then
the circuit breaker should be derated using the table below. For IEC 60947-2 standard, the products carry an ambient rating of 30 °C. Follow standard
IEC application considerations for temperature rating in different ambient temperatures.

Note: Application below 0º C is for non-condensing atmosphere. Care should be taken for applications below 0 °C. These devices are not certified to oper-
ate correctly in the presence of ice.
