🔍 Key Concepts

• Catalog number structure on Illustration EL-0180 (what each letter/number position represents) • How NEMA size and continuous amperes match to the contactor frame size suffix (A,B,C,D, etc.) • How to select the correct OLR type and feature set (electronic C440 with ground fault) and coil voltage suffix (24 VAC/60 Hz)

💭 Think About

• Start by matching the required continuous amperes (45 A) to the proper NEMA size and its catalog suffix on the left side of the chart. Which letter corresponds to 45 A? • Next, identify which character position in the example catalog number controls reversing vs non‑reversing, and which choices show the correct digit for a reversing starter. • Look at the sections for OLR Type and C440 OLR Designation. Which combination gives an electronic overload with a ground fault feature set and then check which of the answer choices contain those codes. • Finally, use the AC Coil Suffix table to find the correct letter for 24 V, 60 Hz and eliminate any options that do not use that suffix.

✅ Before You Answer

• Verify that the selected contactor frame size suffix matches exactly to 45 continuous amperes per the chart. • Confirm the digit/letter that indicates reversing is correct and appears in the same position as in the example catalog number. • Double‑check that the OLR portion of the code shows C440 electronic overload and specifically the ground fault feature set, not the standard set. • Ensure the final letter for the coil code matches 24 V, 60 Hz; any other voltage or frequency combination is not acceptable.
