Description

Power contactor, AC-3 65 A, 30 kW / 400 V 1 NO + 1 NC, AC / DC 20-33 V, with 3-pole varistor, size S2 Screw connection SIRIUS 3RT2 power contactor for switching motors.
The 3RT2 contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress through their high performance while at the same time compact design and high contact reliability. They can be combined with other components in the load feeder in many ways. Many of the device combinations are factory tested. The contactors offer the optimum connection to the controller for each application (parallel, via ASi or IO-Link). Integrated auxiliary switches reduce the complexity of your design. The front connections enable easy wiring. The 3RT2 contactors are climate-proof, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready.
They are available in various sizes and in a large power range in AC and DC operation. In addition to screw connection technology, the devices are also continuously available with spring-type terminals for a fast, maintenance-free and vibration-proof connection.
The comprehensive accessories, such as auxiliary switches, auxiliary releases, etc., are uniform for all sizes. The available connection blocks, function modules and the SIRIUS 3RV29 infeed system considerably reduce the wiring effort.
The 3RT2 power contactors replace the proven 3RT1 series (up to 55 kW).
Simple, efficient, always up-to-date - the SIRIUS modular system.
