Design and Performance
Higher-Power Switching for Demanding Motor Applications
As part of the SIRIUS 3RT2 modular contactor system, the 3RT2045-1AP00 handles up to 37 kW at 400 V, delivering reliable direct-on-line switching for larger motors and heavy industrial equipment within the S3 frame size.
Front-Panel Terminals for Simplified Wiring
Front-panel terminals simplify wiring compared to top/bottom terminal designs on conventional contactors, while spring-type terminal versions are also available for fast, maintenance-free, vibration-proof connection.
Climate-Resistant, Globally Approved Design
Climate-resistant and approved for worldwide use (including IEC and UL/CSA) and IE3/IE4-ready, this contactor supports deployment across diverse industrial markets and international motor efficiency standards.
Reduced Wiring Expense with Integrated Accessories
Available link modules, function modules, and the SIRIUS 3RV29 infeed system considerably reduce the wiring expense, streamlining panel assembly for larger motor starter combinations.
Direct Successor to the Proven 3RT1 Series
The 3RT2 power contactors replace the well-proven 3RT1 series (up to 55 kW), offering a simple, efficient, and always up-to-date platform backed by a comprehensive, standardized accessory range across all sizes.
