Square D CC Series Thermal Overload Unit, Melting Alloy, Class 20

Square D CC Series Thermal Overload Unit, Melting Alloy, Class 20

The Square D CC Series thermal overload unit (Type S, Type CC) is a melting-alloy thermal element engineered to protect motors, controllers, and branch-circuit conductors against excessive heating caused by prolonged motor over-currents, up to and including locked rotor currents. This family is offered across seven model selections — CC1120, CC1210, CC1560, CC501, CC594, CC815, and CC940 — each sized to match specific overload relay and starter configurations while sharing the same Class 20 Motor Tripping Class and 600V maximum voltage rating. Manufactured by Schneider Electric, the CC Series is designed for dependable, code-conscious motor branch-circuit protection across NEMA Sizes 00-7 in commercial and industrial applications. Whichever model is selected from the range, the thermal unit delivers consistent melting-alloy overload sensing built to Square D's manufacturing standards.
