Product Description
The Square D A5.30 thermal unit protects motors, controllers, and branch circuit conductors from 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. It features a one-piece construction and is for use in melting alloy thermal overload relays.
- Cannot be reset until cooled
- Melting Alloy Thermal Units
- Calibration is set for a range of motor full load currents
Product Highlights
Provides overload protection for most motors. Repeated tripping does not affect the original calibration.
