Question 1 of 205eccefa4bacbc34ba4d482d3

As shown in the illustrated electronic overload relay, if it is desired to connect the relay to a trip indicator for alarm purposes, what terminals would the trip alarm be associated with in completing the series circuit? See illustration EL-0182.

🔍 Key Concepts

• Identify which terminal pairs on an overload relay are normally used for auxiliary contacts (alarm/indicator) versus supply/control power connections • Understand the difference between a normally closed (NC) trip contact that opens on trip and a normally open (NO) contact that closes on trip • Read the small terminal markings and contact symbols printed near terminals 95-96-97-98, A3+, A4- on the illustration

💭 Think About

• Which terminals on this relay are clearly grouped and labeled as a set of changeover contacts (common, NC, NO) specifically intended for signaling a trip condition? • If you wanted the alarm circuit to be in series and energize only when the relay trips, would you use the NC contact (opens on trip) or the NO contact (closes on trip)? • Looking at the illustration, which pair of terminals share the same small contact symbol as the one labeled with the trip indication legend?

✅ Before You Answer

• Verify which terminals in the picture are labeled 95-96-97-98 and how they are grouped • Check whether A3+ and A4- are associated with control power or with alarm signaling in the diagram on the relay • Confirm from the printed symbols which pair of terminals forms the series contact that changes state on trip for use with an indicator or alarm
