Product Description

Square D B28.0 thermal unit is designed to protect motors, controllers, and branch circuit conductors from excessive heating caused by prolonged motor over-currents, including locked rotor currents. These thermal units operate based on trip curves and will trip in twenty seconds or less under overload conditions. The one-piece construction allows motor current to pass through a small heater winding, triggering a melting solder mechanism. When an overload occurs, the solder melts, spinning a ratchet wheel that opens the control contacts, disconnecting the motor. The AIC Rating in accordance with UL512 is two hundred thousand Amps, ensuring high reliability in various applications.

  • Cannot be reset until cooled.
  • Available in designs: standard trip (Class 20), slow trip (Class 30), quick trip (Class 10).
  • Calibration set for a range of motor full load currents.

Product Highlights

This thermal unit provides essential overload protection for most motors and maintains its original calibration even after repeated tripping.
