Frequently asked questions
Will the 5SJ4320-7HG42 fit a panel specified for the 5SJ4316-7HG42?
Physically yes – same DIN-rail footprint, same modular width, same height and depth. No rewiring needed for panel layout. But verify the ampacity: 20 A vs 16 A changes the protection coordination.
What compliance documentation does Siemens provide for the 5SJ4320-7HG42?
The part is halogen-free, silicon-free, and sealable. It is rated for vibration resistance and overvoltage category III per EN/IEC standards. For specific declarations (RoHS, REACH, UL), refer to the manufacturer's current documentation or our sales team – these are not in the basic spec listing but are standard for this series.
