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
