BULLETINcmT&wPRODUCTI 815DATATYPEN HEATERELEMENTSHEATERELEMENTSELECTION- The “Full Load Amps.” listed inthe tables are to be used for heater element selection. Therating of the relay in amperes at 40” C is 115% of the “Full LoadAmps.” listed for the “Heater Type No.”Refer to the motor nameplate for the full load current, theservice factor, and/or the motor classificationby applicationand temperature rise.Use this motor nameplate information, the application rules,and the “Full Load Amps.” listed in the proper table (see Indexon Page 2) to determine the “Heater Type No.”OVERLOADRELAY CLASS DESIGNATIONS- Industry standards(NEMA Part ICS 2-222) designate an overload relay by a classnumber indicating the maximum time in seconds at which it willtrip when carrying a current equal to 600 percent of its currentrating.MOTORSRATEDMOTORSMOTORSWITH MARKED SERVICE FACTORWITH A MARKED TEMPERATURESpecific Applicationsmay require Class 10 or Class 30overload relays. Class 10 overload relays are often used withhermetic motors, submersiblepumps, or motors with shortlocked rotor time capability. Class30 overload relaysshould beused with motors driving high inertia loads where additionalaccelerating time is needed.For applicationregarding Class 10 and 30 overloadconsult local Allen-Bradleyoffice.relays,OF NOT LESS THAN 1.15, ORRISE NOT OVER 40 C.- If theat the Controller than at the Motorfull load current value shown on the motor nameplate isbetween the listed “Full Load Amps.“, select the “HeaterType No.” with the higher value. This will provide integralhorsepower motors with protection between 115 and 125%of the nameplate full load currents.2. Higher Temperature3. Lower Temperature- If theat the Controller than at the Motorfull load current value shown on the motor nameplate isbetween the listed “Full Load Amps.“, select the “HeaterType No.” with the lower value. This will provide integralhorsepower motors with protection between 105 and 115%of the nameplate full load currents.A Class 30 overload relay will trip in 30 seconds or less at acurrent equal to 600 percent of its rating.Allen-Bradleystandardoverloadrelay protectionusingeither Type N or W heater elements provide Class 20 operationand are recommendedfor General Application.DUTY:1. The Same Temperatureat the Controller and the Motor - Selectthe “Heater Type No.” with the listed “Full Load Amps.”nearest the full load value shown on the motor nameplate.This will provide integral horsepower motors with protection between 110 and 120% of the nameplate full loadcurrents.A Class 10 overload relay will trip in 10 seconds or less at acurrent equal to 600 percent of its rating.A Class 20 overload relay will trip in 20 seconds or less at acurrent equal to 600 percent of its rating.FOR CONTINUOUSALL OTHERMOTORSRATED FOR CONTINUOUSDUTYMOTORS WITH MARKED SERVICEFACTOR OF 1.01:(INCLUDESSelect the “HeaterType No.” one rating smaller thandetermined by the rules in paragraphs 1, 2 and 3.
