Schneider Electric 1CC59.40 Thermal Overload Heater Element

1CC59.40 is a Square D/Schneider Electric thermal overload heater element designed for CC-series overload relays, providing the heating element used in melting-alloy thermal units to protect motors. It is specified for a nominal current rating of 40 A, with an operating window of roughly 35–41.7 A, aligning with CC59.4 heater elements used in Square D motor-control assemblies. This heater element is intended for use with CC-series thermal overload relays, as well as compatible magnetic motor starters and motor controls in the CC family, enabling integrated overload protection within a compact form factor. The component measures approximately 2.40 inches in length, a size that fits standard CC thermal-unit housings, and the 1CC59.40 designation identifies the 40-amp variant within the CC heater lineup.
