File E47705 Vol. 7 Sec. 8 and Report *Page 1 Issued: Revised: 8-22-97 10-4-01 DESCRIPTION PRODUCT COVERED: USL, CNL - Type No. 3RV1041, 3RV1042, 3RV1142, 3RV1341, 3RV1342 or 3RV1641, followed by combination of 4 and a letter A through M, followed by A, B, C or K followed by 1 or 3. May be followed by additional numbers and letters for manufacturer’s use. GENERAL: Type 3RV1041 devices are open type 3-pole manual motor controllers for starting and stopping motors which may be connected directly across the line. They are adjusted over a small range as indicated in the setting range table. They are provided with integral ambient compensated, non replaceable thermal trip features and are suitable for providing overload protection (Class 10 or Class 20) and motor disconnect. The trip current is 125 percent of the FLA shown on dial. Type 3RV1142-... is similar to Type 3RV1041 series device but with no motor overload function. The internal overload tripping system does not trip the controller however it trips the attached trip module for indication to remote panels. Type 3RV1341 devices are similar to Types 3RV1041 except the thermal overload protection is out of function. Type 3RV1042 devices are similar to Types 3RV1041 except rated for short-circuit 100 kA at 400 V. Type 3RV1342 devices are similar to Types 3RV1341 except rated for short-circuit 100 kA at 400 V. Type 3RV1641 devices are similar to Types 3RV1041 except the thermal overload trip is adjusted to Class 5. These devices may be provided with certified accessories of Type 3RVl9.. including auxiliary switches, bus bar assembly, tripping units and short circuit indicators.
