Description
Siemens 3RT12646AB36
vacuum contactor, AC-3 225 A, 110 kW / 400 V AC (50 ... 60 Hz) / DC control UC 23-26 V, auxiliary contacts 2 NO + 2 NC, 3-pole, size S10, drive busbar connections: conventional SIRIUS 3RT12 vacuum contactor for controlling motors.\nThe 3RT12 vacuum contactors are an integral part of the SIRIUS modular system with perfectly coordinated products. They convince with great power in a compact design and high contact reliability. Vacuum contactors are also characterized by a particularly long service life. They are therefore particularly suitable for frequent maneuvers in pulse operation. It is possible to combine them in many ways with other components in the startup. The contactors offer the optimal connection to the controller for each application (direct or via PLC input). Pre-assembled auxiliary switch blocks reduce mounting complexity. The 3RT1 contactors are tropicalized, have international approvals (e.g. IEC and UL/CSA) and are IE3/IE4ready.\nThese relays are available in different sizes and with a wide power range. They have a wide DC voltage range and an input for PLC control. In the main circuit it is possible to connect the devices via busbars or cable clamps. For the auxiliary and control circuit, they can also be supplied with spring-loaded terminals for quick, maintenance-free and shock- and vibration-resistant connection.\nNumerous accessories are available for these contactors, such as e.g. wiring kits, which significantly reduce the wiring effort, auxiliary switch blocks or terminal covers.\nSimple, efficient, always up-to-date - the SIRIUS modular system.
