Applications

The 3RV1915-1BB is ideal for power distribution in motor control centers, industrial automation panels, and electrical control systems where multiple motor starter protectors need to be fed from a common power source. It provides efficient power distribution for three motor protection devices in applications such as conveyor systems, pump stations, HVAC equipment, manufacturing machinery, and process control installations requiring organized and space-efficient motor starter protector arrangements.

Operation

The busbar system provides a common power supply to three motor starter protectors through fork-shaped connections that ensure reliable electrical contact. Power is distributed through the insulated copper busbars to each connected motor starter protector position. The 45mm modular spacing allows for standard side-by-side mounting of SIRIUS motor starter protectors. Installation involves mounting the busbar on DIN rail and connecting the motor starter protectors to the fork connections, eliminating the need for individual power wiring to each device.
