File E156943 Vol. 1 Sec. 12 and Report Page 1 Issued: Revised: 1998-01-19 2003-06-05 DESCRIPTION PRODUCT COVERED: USL, CNL - Open Type Self-Protected Combination Motor Controllers, Cat. No. 3RV1031 followed by combination of 4 and the letter A, B, D, E, F, G or H, followed by A1 or A3, followed by 0, 1, 2, 3, 4, 5 or 8, may be followed by additional numbers and letters. GENERAL: These device are open type manual combination motor controllers. They are intended to provide motor disconnection means, motor branch-circuit shortcircuit and ground fault protection, motor control, and motor overload *protection. These devices are suitable for use as Service Equipment. These devices may also be used with Siemens Listed type 3RT contactors and 3RW *solid state controllers. When used, the contactors and solid state controllers have the same horsepower rating as the 3RV1031 devices with which they may be used.
