RA, RA Contactor Assemblies RA Contactor Assemblies for Wye-Delta Starting RA complete units,... kw Siemens AG 0 Overview These RA contactor assemblies for wye-delta starting are designed for standard applications. Note: Contactor assemblies for wye-delta starting in special applications such as very heavy starting ) or wye-delta starting of special motors must be customized. Help with designing such special applications is available from Technical Assistance. The RA contactor assemblies for wye-delta starting can be ordered as follows: Sizes S00 to S: Fully wired and tested, with electrical interlock, dead interval of s on reversing (size S00 with electrical and mechanical interlocks). Sizes S00 to S: As individual parts for customer assembly. A dead interval of 0 ms on reversing is already integrated in the time relay function. There is also a range of accessories (auxiliary switch blocks, surge suppressors, etc.) that must be ordered separately. For overload relays for motor protection see "Protection Equipment" "Overload Relays" "RB Solid-State Overload Relays". The RA contactor assemblies have screw terminals and are suitable for screw and snap-on mounting onto mm standard mounting rails. Fully wired and tested RA contactor assemblies have one unassigned NO contact which is mounted onto the front of the K delta contactor. A solid-state time-delay auxiliary switch block is snapped onto the front of the complete contactor assemblies, size S00. kw, while a timing relay is mounted onto the side of sizes S0 to S, kw to kw.

Siemens AG 0 RA, RA Contactor Assemblies RA Contactor Assemblies for Wye-Delta Starting RA complete units,... kw Components for customer assembly s with wiring modules and, if necessary, mechanical connectors are available for contactor assemblies for wye-delta starting. Contactors, overload relays, wye-delta timing relays, auxiliary switches for electrical interlock if required also feeder terminals, mechanical interlocks (exception: In the case of the assembly kit for size S00 contactor assemblies the mechanical interlock between the delta contactor and the star contactor is included in the kit) and base plates must be ordered separately. The wiring kits for sizes S00 and S0 contain the top and bottom main conducting path connections between the line and delta contactors (top) and between the delta and star contactors (bottom). In the case of sizes S to S only the bottom main conducting path connection between the delta and star contactors is included in the wiring module, owing to the larger conductor cross-section at the infeed. Motor protection Overload relays or thermistor motor protection tripping units can be used for overload protection. The overload relay can be either mounted onto the line contactor or separately fitted. It must be set to 0. times the rated motor current. Note: The selection of contactor types refers to fused configurations (see note on Technical Information on page /).
