Siemens 3RT1276-6AR36 contactor 250kW/400V/AC-3

Vacuum contactor, AC-3 500 A, 250 kW / 400 V AC (50-60 Hz) / DC operation UC 440-480 V Auxiliary contacts 2 NO + 2 NC 3-pole, size S12 Busbar connections Drive: conventional Vacuum contactor SIRIUS 3RT12 for switching motors. The 3RT12 vacuum contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress with their high performance combined with a compact design and high contact reliability. The vacuum contactors are also characterized by a particularly long switching life. They are therefore particularly suitable for frequent switching in inching mode. They can be combined in many ways with other components in the load feeder. The contactors offer the right connection to the control system for every application (directly or via PLC input). Pre-assembled auxiliary switches reduce the complexity of your setup. The 3RT1 contactors are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready. They are available in various sizes and in a wide power range. They have a wide DC voltage range and a PLC control input. In the main circuit, the devices can be connected via rails or box terminals. For the auxiliary and control circuits, they are also available with spring-loaded connections for a quick, maintenance-free and vibration-proof connection. There are a wide range of accessories for these contactors, such as wiring kits that significantly reduce the wiring effort, auxiliary switches or terminal covers. Simple, efficient, always up-to-date - the SIRIUS modular system.
