Question 1 of 205eccefa4bacbc34ba4d482d5

As shown in the illustrated electronic overload relay, if the external current transformers transform current on a basis of 100:1, what is the actual full load current setting as presently set? See illustration EL-0183.

🔍 Key Concepts

• How to read the LOAD (A) dial setting on the electronic overload relay faceplate • Relationship between current seen by the relay and current in the primary circuit when using current transformers (CTs) • Using the CT ratio 100:1 to scale the dial setting to the actual full‑load current

💭 Think About

• First, what exact ampere value is indicated by the LOAD (A) adjustment knob in the illustration? Is it less than 1 A, a few amps, or tens of amps? • If the relay is adjusted in terms of the secondary current of the CT, how does a 100:1 ratio change that number when referred back to the motor line current? • After applying the 100:1 factor, which answer choice most closely matches your calculated actual full‑load current?

✅ Before You Answer

• Verify the numerical position of the LOAD (A) pointer on the dial from the illustration (between which numbers is it set?). • Confirm whether the CT ratio means Primary : Secondary = 100 : 1 and therefore whether you should multiply or divide by 100 to get line current. • Before choosing, check that your final value’s order of magnitude (tenths, units, tens, hundreds of amps) matches the scaled result from the dial reading.
