Product Description
The Square D A2.81 Thermal Unit is designed to protect motors, controllers, and branch circuit conductors from overheating due to extended motor overcurrents, including locked rotor currents. This unit also aids in safeguarding the motor and other branch circuit elements from high currents from short circuits or grounds using branch circuit fuses or circuit breakers.
- Provides overload protection for most motors.
- Tripping occurs in 20 seconds or less under overload conditions.
- Features one-piece thermal unit construction.
Product Highlights
This thermal unit effectively responds to overload conditions according to trip curves. The unit utilizes a heater winding and melts a special solder under overload, allowing for the opening of control circuit contacts.
