User & Safety Instructions 2863575 Siemens 3RT2026-2DB40 Contactor 1 maker, 1 breaker 40 kW 690 V 22 A + varistor Compatible with (relay brand): Siemens 1

Description

Power contactor, AC-3e/AC-3, 25 A, 11 kW / 400 V, 3-pole, DC 24 V, with inserted varistor, auxiliary contacts: 1 S + 1 NC, spring-loaded connector SIRIUS 3RT2 power contactor for switching motors.
The 3RT2 contactors are part of the SIRIUS modular system with their optimally coordinated products. They convince by high power with a compact design and high contact reliability. They can be combined in a variety of ways with other components in the load feeder. Many of the device combinations have been tested at the factory. The contactors provide optimum connection to the controller (parallel, via ASi or IO-Link) for each application. Integrated auxiliary switches reduce the complexity of your setup. The front connections allow simple wiring. The 3RT2 contactors are climate-proof, worldwide approved (e.g. IEC and UL/CSA) and IE3/IE4ready.
They are available in various sizes and in a wide power range with AC and DC actuation. Apart from screw connection technology, the devices are also available continuously with spring connection for a fast, maintenance-free and vibration-proof connection.
The comprehensive accessories, such as auxiliary switch, auxiliary release, etc. are uniform for all sizes. The available connection modules, function modules and the SIRIUS 3RV29 infeed system considerably reduce the wiring effort.
The 3RT2 contactors replace the tried-and-tested series 3RT1 (up to 55 kW).
Simple, efficient, always up-to-date - the SIRIUS modular system.
