Siemens Selectivity Module, for use with SITOP

To prevent work from halting due to a fault in one of your electrical branches, fit this selectivity module from Siemens. It selectively protects the various circuits connected to your primary 24V DC power supply, so reliably disconnects a faulty load while allowing others to continue uninterrupted. Individually adjustable output thresholds mean you can set each feeder to your specific needs. LED indicator lights allow you to quickly assess your various output statuses. To stop false tripping, the unit allows for brief current peaks. It's suitable for use in automated industrial production applications when combined with switch-mode power supplies from the Siemens SITOP range.

• Reliable tripping, regardless of the length or cross-section of your cables
• Suitable to use in hazardous locations where explosive atmospheres may be present
• Snaps onto a DIN rail for quick and tool-free mounting
• Screw terminals that hold wires securely in place to reduce the need for regular maintenance checks

You can use this module in operating temperatures between -25°C and +60°C, so it's suitable for demanding settings.
