Information

Overview Manuals Common Applications Product Precautions

The 3RT6015-1BB41 is an ultra-compact three-pole power contactor from the Siemens SIRIUS series. Specifically designed for controlling small motors and inductive loads, it is a core component in automation control cabinets for realizing "PLC direct drive of power loads".

PLC direct drive
Ultimate space utilization
Exceptional reliability and ultra-long lifespan

SIRIUS is Siemens' flagship industrial control system for industrial automation, with its core concept being to provide a comprehensive modular solution encompassing switching, starting, protection, and monitoring. The system includes core components such as contactors, motor protection circuit breakers, thermal overload relays, and soft starters. With its extremely high space utilization, quick wiring technology, and excellent mechanical and electrical lifespan, it can easily handle various complex motor control tasks. Through standardized, modular assembly, the SIRIUS series not only simplifies the design and assembly of control cabinets but also ensures the stability and safety of industrial systems under high-frequency operation, setting an industry benchmark for modern automation control architecture worldwide.

Food Processing

Receives timing signals to drive agitator blade motors in industrial baking equipment, ensuring standardized dough processing.

Machine Tools

When the spindle rotates, the PLC drives the contactor to start the coolant circulation pump, cooling the cutting zone and flushing away metal chips.

Automotive

Synchronously starts localized exhaust fans above welding stations when the robot begins operation to protect environmental air quality.

Water Treatment

Controls dosing pumps based on water quality monitor signals to accurately inject chemicals for pH adjustment or disinfection.

EMS

Controls small pumps to maintain the height of the solder wave, ensuring the welding reliability of electronic component pins.

Water Treatment

Operating chemical dosing pumps in localized filtration systems.

When using the Siemens 3RT6015-1BB41, ensure the control supply is a stable 24V DC; while it can be driven directly by a PLC due to its low power consumption (approx. 4W), adding a diode surge suppressor is highly recommended to protect the controller from back-EMF. Secondly, strictly adhere to the Size S00 current limits (7A/3kW max under AC-3) to avoid contact erosion from overloading. Finally, given its compact size and high-frequency operation, maintain a clean installation environment and regularly check the screw terminals for tightness to ensure reliable electrical connections under vibrating conditions.
