Applications

The 3RV1915-2CB is ideal for power distribution in motor control centers, industrial automation panels, and electrical control systems where four motor starter protectors with accessories need to be fed from a common power source. It provides efficient power distribution for motor protection devices equipped with auxiliary switches 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 with enhanced monitoring capabilities.

Operation

The busbar system provides a common power supply to four 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 55mm modular spacing allows for motor starter protectors equipped with lateral auxiliary switches and other accessories. 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 while accommodating auxiliary equipment.
