Design and Performance

Reliable Motor Switching in a Compact Size S0 Footprint

As part of the SIRIUS 3RT2 modular contactor system, the 3RT2027-2BB40 delivers dependable direct-on-line motor switching up to 15 kW at 400 V, with high contact reliability in a space-efficient design.

Fast, Maintenance-Free Wiring

Spring-type terminals provide vibration-proof, tool-minimal connections, simplifying installation and reducing long-term maintenance compared to traditional screw terminals.

Integrated Auxiliary Contacts for Signaling and Interlocking

Built-in 1 NO + 1 NC auxiliary contacts support status signaling, interlocking, and control circuit feedback without requiring a separate auxiliary contact block.

Climate-Resistant, Globally Certified Design

Approved for worldwide use under IEC and UL/CSA standards and IE3/IE4-ready, this contactor is built to perform reliably across diverse industrial environments and motor efficiency classes.

Expandable SIRIUS Modular System

Compatible with the broader SIRIUS 3RT2 accessory range — including function modules for communication, auxiliary switches, and the 3RV29 infeed system — allowing the contactor to scale into more complex motor control and monitoring setups as needed.
