Siemens 3-Pole Contactor, 25A, 24V DC Coil Voltage - 3RT2 Series - 3RT2026-2BB40
As part of Siemens' innovative SIRIUS modular system, this compact contactor will save space in your electrical cabinet. It's been designed for use with the new IE3/IE4 generation of motors and offers efficient and flexible power distribution along with high resistance to vibrations. The 24V DC coil means you can operate it from a UK mains supply without the need for a transformer. Thanks to a contact voltage rating of 400V AC and contact current rating of 25 A, you can use it to switch high-powered loads.
• Operating temperature range of -25°C to +60°C for reliable use in harsh industrial settings
• Innovative cage clamp terminals use a unique patented mechanism to automatically connect solid or stranded wires
• Innovative cage clamp terminals use a unique patented mechanism to automatically connect solid or stranded wires
Why choose cage clamp terminals?
Cage clamp terminals substantially cut the time needed to wire up contacts. They don't need any judgement from the installer to make the connection correctly, unlike screw connections that need to be tightened to the required level. This makes them easier for operators of all levels of expertise to install in the field.
