Frequently asked questions
How do I get current pricing and availability for 5SY4101-7KK11?
Submit an RFQ against this order code. Pricing and stock are confirmed at quote time through our independent distribution network.
Will 5SY4101-7KK11 drop into a panel specified around 5SY4101-7CV without rewiring?
Both are 1-pole, 1 A, C-curve SENTRON MCBs in the same 18 mm footprint with the same DIN-rail mounting, so they are mechanically interchangeable. The 5SY4101-7KK11 carries a railway-application designation and a 35 kA IEC 60947-2 rating; the 5SY4101-7CV may have a different breaking capacity or environmental rating — verify the panel's SCCR requirement before swapping.
What is 5SY4101-7KK11's listed depth?
The overall depth is 76 mm; the installation depth behind the panel is 70 mm.
What is 5SY4101-7KK11's listed width?
The width is 18 mm, which is one modular unit (1 MW) for a 1-pole MCB.
