Design and Performance
Integrated Varistor for Enhanced Coil Protection
A built-in varistor suppresses voltage spikes generated during coil de-energization, protecting the control circuit and extending coil life without requiring an external surge suppressor accessory.
Wide Voltage AC/DC Coil for Flexible Control Compatibility
Operating across a 20-33 V AC/DC range, this contactor’s coil accommodates both AC and DC control circuits within a single reference, simplifying specification across mixed-voltage control architectures.
Higher-Power Switching in a Compact S2 Frame
Delivering 18.5 kW at 400 V in Size S2, this contactor extends the SIRIUS 3RT2 range to larger motor applications while retaining a narrow design and high contact reliability.
Climate-Proof Design for Worldwide Use
As part of the 3RT2 range spanning sizes S00 to S2 up to 37 kW, this contactor is climate-proof and suitable and tested for use worldwide, supporting deployment across diverse operating environments.
Flexible SIRIUS Modular System Compatibility
A large array of easily installed, standard accessories — including auxiliary contact blocks, overload relays, and interlocking kits — allows this contactor to be customized for different application needs within the modular SIRIUS system.
