It features a 110 V DC coil for control power and integrated auxiliary contacts, making it a complete solution for modern control systems.

Benefit

• High Reliability: Part of the Siemens SIRIUS range, ensuring long mechanical and electrical service life.
• Fast, Secure Wiring: Spring-loaded terminals provide fast, tool-free, and permanent connection, significantly reducing wiring time and preventing connection failures due to vibration.
• Space-Saving Design: The compact S00 size allows for high packing density in control cabinets.
• Motor Protection Ready: Suitable for standard motor switching applications and easily combinable with SIRIUS 3RV2 motor starter protectors.

Function

The Siemens 3RT2015-2BF48-3MA4 is primarily used for switching 3-phase AC motors and resistive loads. The 110 V DC coil is energized by a control signal, which then closes the 3 main power poles, allowing current to flow to the load. The auxiliary contacts provide feedback or interlocking signals to the control system. The spring-loaded terminal ensures a gas-tight, reliable connection for both the main circuit and the control circuit.
