Siemens 3TX7119-5LB03 Plug-In Relay DPDT 12VDC 20A 8 Pins

Siemens 3TX7119-5LB03 Premium Plug-In Relay is a DPDT (double-pole, double-throw) control relay with a 12 VDC coil and a 20 A contact rating, designed for quick replacement in Siemens 3TX71 plug-in relay sockets. This eight-pin module is specified for use with the 3TX7144-4E4 socket (Premium style) and is compatible with the 1L12 retention clip for secure panel mounting. The DPDT configuration provides two independent switching circuits in a compact package, suitable for controlling motors, solenoids, or other loads in automation and building-control applications, where reliable low-voltage actuation and higher current capability at 12 VDC are required. The LB03 suffix identifies the premium variant within Siemens’ catalog, and ordering guidance typically emphasizes matching the socket (3TX7144-4E4) and accessory set to ensure proper fit and reliable operation in your control cabinet or panel. When integrating, verify that your circuit load stays within the 20 A rating per pole and confirm compatible accessories to maintain interchangeability with other 3TX71 plug-in relays.
