Square D CC103.0 Thermal Unit

Product Description

The Square D CC103.0 Thermal Unit provides essential overload protection for motors and controllers. It is designed to prevent excessive heating caused by prolonged motor over-currents, including locked rotor currents. The unit features a one-piece construction that allows motor current to flow through a heater winding. When an overload occurs, heat causes a solder to melt, enabling a ratchet wheel to rotate and open the control circuit, thus protecting the motor.

• Designed for Class 20 overload conditions
• Responds in 20 seconds or less to trip on overload
• One-piece construction for durability

Product Highlights

This thermal unit is critical for the safety and efficiency of electrical systems, ensuring that components remain protected during overload events.
