The Siemens 3TH2244-0BB4 is a robust contactor relay designed for a wide range of industrial applications. This component is engineered to facilitate reliable switching of auxiliary circuits and control signals within electrical systems. With a configuration of 4 normally open (NO) and 4 normally closed (NC) contacts, it offers versatility for complex circuit designs.
Featuring a control supply voltage of 24 V DC, the 3TH2244-0BB4 is suitable for DC operation and comes with a screw terminal connection for secure and straightforward installation. The compact dimensions, with a width of 45 mm, allow for efficient use of space inside control cabinets.
This contactor relay is built to the EN 50011 standard, ensuring compatibility with European installations, and is rated for operating currents of 4 A at 230 V in AC-15 usage, and 3 A at 400 V, making it a practical choice for a variety of control tasks. The device is also finger-safe, providing protection against electrical shock and enhancing safety during handling and operation.
Mounting is made easy with options for both screw and snap-on mounting onto a 35 mm standard mounting rail according to DIN EN 50022. The 3TH2244-0BB4 is a discontinued product, and its successor is the SIRIUS 3RH21 series, which continues Siemens' tradition of innovation and reliability in contactor technology.
