SIEMENS Busbar 3-Phase 55mm Pitch 63A 690V for SIRIUS 3RV2 3RV19152AB

When building motor starter groups, connecting multiple circuit breakers individually creates wiring complexity and potential failure points. The SIEMENS 3RV19152AB busbar solves this by providing a direct plug-in power distribution link for two 3RV2 devices with a 55 mm pitch, eliminating individual wiring and reducing assembly time.

Who is it for

Industrial electricians and panel builders who need to supply power to multiple SIRIUS 3RV2 motor starter protectors in a compact, reliable manner. It suits control cabinets where space is limited and consistent electrical connection is critical.
