Product Description
The Square D CC59.4 thermal unit protects motors, controllers, and branch circuit conductors from excessive heating due to prolonged motor over currents, including locked rotor currents. These Class 20 thermal units respond to overload current conditions according to trip curves, tripping in 20 seconds or less. The motor current passes through a small heater winding, and under overload conditions, heat melts a special solder, opening the control circuit contacts.
- Melting alloy thermal units available in standard trip (Class 20), slow trip (Class 30), and quick trip (Class 10) designs.
- One-piece thermal unit construction.
- Provides overload protection for most motors.
Product Highlights
Provides overload protection for motors, controllers, and branch circuits. Features one-piece construction and melting alloy design.
