Frequently asked questions

What is the breaking capacity of 5SY4315-7KK11?

35 kA per IEC 60947-2 and 10 kA per EN 60898. The IEC 60947-2 figure governs industrial panel SCCR; the EN 60898 figure applies in residential/commercial distribution boards.

Will 5SY4315-7KK11 drop into a panel specified around 5SY4140-7?

Physically yes — same 3-pole, 3-module-width DIN-rail footprint, same 76 mm depth. The difference is rating: 5SY4140-7 is a higher-current variant. No rewiring needed for the same physical slot, but verify the load current against the 1.6 A rating of this part.

What compliance documentation does Siemens provide for 5SY4315-7KK11?

The part carries IP20 protection class, overvoltage category III, and degree of pollution 3. It is halogen-free and silicon-free. Standard Siemens declaration of conformity covers IEC 60947-2 and EN 60898. RoHS/REACH declarations are available on request.

Where can I buy 5SY4315-7KK11 and how is it quoted?

Sourced to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time. For volume or blanket orders, the same genuine part can be cross-referenced across regions.
