No. 3RV1041 or 3RV1042, followed by up to 3 digits, followed by F, H, J, K, L or M, followed by A or B, followed by 1 or 3, followed by 0, 1, 2, 3, or 8, may be followed by additional numbers and letters. 3RT1946-4GA07 Line Terminal Adapter. GENERAL: These device are open type manual combination motor controller. 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 3RV1021 devices with which they may be used. Type 3RV1042 devices are identical to the Types 3RV1041. is for marketing purposes only. The name change These devices are provided with line terminal adapters cat. no. 3RT1946*46A07. The adapters may be factory or field-installed. (See “Marking” section).
