Product Description
The Square D B2.40 thermal units protect motors, controllers, and branch-circuit conductors against excessive heating due to prolonged motor over-currents, including locked rotor currents. Class 20 thermal units respond to overload current conditions according to trip curves, tripping in 20 seconds or less. These units feature a one-piece construction.
- Provides overload protection for most motors
- Cannot be reset until cooled
- Calibration is set for a range of motor full load currents
Product Highlights
These melting alloy thermal units are available in standard, slow, and quick trip designs. They protect against excessive heating and trip quickly under overload conditions.
