Siemens Contactor, NO/NC Auxiliary Contact Configuration, 1.8W Total Power Loss - SIRIUS Innovation Series - 3RT2025-2BB40
This contactor from Siemens lets you safely control switching devices in your commercial and industrial circuits. A 17A current rating means it can handle the large loads needed to effectively manage high-current machines. The unit uses a 24V DC coil, which helps minimise user exposure to dangerous electricity levels and supports safe switching. As it has three protective poles to handle up to three circuits, it's a convenient option for system control. A closing delay between 50 and 170ms means you enjoy quick response times and efficient process activation. You'll find a contactor like this one used with motor starters and large lighting systems.
Features & Benefits
• Spring cage terminals help secure electrical connections against jostling
• Power loss of 0.6W per pole for energy-efficient machine control
• Typical mechanical service life of ten million cycles for longevity
• Operating frequency of up to 1,000 cycles per hour to suit demanding switching applications
• Power loss of 0.6W per pole for energy-efficient machine control
• Typical mechanical service life of ten million cycles for longevity
• Operating frequency of up to 1,000 cycles per hour to suit demanding switching applications
How do I mount this contactor?
This unit clips onto a DIN rail, so installation is quick and simple. You can rotate the contactor by 180° and tilt it forwards or backwards by up to 22.5° to suit the space in your cabinet.
