SITOP SEL1200 24V Switching Selectivity Modules
Siemens SITOP SEL1200 24V Switching Selectivity Modules have a switching characteristic for standard protection. The devices provide electronic protection and fast fault localization in 24VDC load circuits. Siemens SITOP selectivity modules distribute the load current across several 24VDC load circuits and reliably monitor them for overload and short-circuit conditions. SEL1200 selectivity modules allow higher brief overload currents. The higher the current, the faster the output is shut down. These selectivity modules support loads with high inrush current through which the supply voltage can drop to 15V. Users can switch the signaling of the SITOP SEL1200 between common signaling and channel-specific diagnostics.
