The Square D LC1D38BLS177 is a Tesys D IEC magnetic contactor rated for 38 A. It belongs to the IEC contactor category and is classified as a magnetic contactor sub-category, meaning it uses an electromagnetic coil to switch power circuits — standard for motor starting and lighting/heating loads in industrial control panels.
What the 38 A rating means for fit
The 38 A rating is the IEC thermal current (Ith) or AC-1 resistive load current. For motor duty (AC-3), the actual switching current will be lower — typically around 18–20 A for a 7.5 kW motor at 400 V. Verify the coil voltage and auxiliary configuration before committing to the BOM line.
