Siemens CXL203 Contactor

Siemens CXL203 Contactor is a legacy Siemens-Allis motor-contactor used to switch high-current loads in industrial control panels. It belongs to the CXL family and provides the main current path for starting and stopping AC motors, pumps, and fans in industrial settings. It is designed to be used with standard Siemens control components, including overload relays and auxiliary contact blocks in motor starter assemblies to provide power switching and signaling. The CXL203 is built for reliable operation under typical industrial conditions, with durability for repeated on/off cycles in automated equipment. When replacing or cross-referencing, check the coil voltage, the number of main poles, and the configuration of auxiliary contacts against Siemens catalogs or a trusted distributor, as precise specifications vary within the legacy CXL line.
