At J&L, our part numbers aren’t just for the warehouse. They’re designed to help you understand exactly what you’re getting — without digging through a spec sheet.
Let’s take this example:
HVFD3B3C0150G131B
That code tells us everything — from voltage and bypass type to HP and NEMA rating. And the most important part? The final digits.
Let’s bring it to life.
We’ve created an example of how each section of a part number maps to real product specs.
Take a look below.
Now That You’ve Seen It, Let’s Break It Down:
💡The last three digits tell you the NEMA rating, number of contactors, and bypass type — the core of the configuration.
💡Horsepower (HP) is always shown as a four-digit number with an extra zero.
For example:
0150 = 15 HP
0400 = 40 HP
This format also allows us to support fractional HP values, like 1.5 or 7.5.
This simple, structured approach helps you quote faster, spec smarter, and speak our language with confidence.
