Product Description
Square D B0.81 Thermal Unit is designed to protect motors and controllers from overheating caused by motor overload currents. This unit operates by tripping to prevent excessive heat, ensuring safety for connected components. It features a one-piece construction where the motor current passes through a heating element which melts solder under overload conditions. This action opens control circuit contacts to prevent motor damage.
- Protects against prolonged motor overloads
- Trips within twenty seconds on overload conditions
- Selected using motor full load current
