Product details

63 A C-curve — the selection mistake this avoids

The 5SY4363-7: Picking the wrong curve means nuisance trips on startup or inadequate fault protection; this one lands in the middle where most panel designs live.

Breaking capacity — 10 kA vs 15 kA, same hardware

At DC per IEC 60947-2 it also holds 15 kA.

Mounting position is unrestricted.

The 5SY4363-7 is a standard catalog line within the SENTRON family, so it is sourced through normal Siemens distribution channels. No official successor or cross-reference exists; this is the active part for the 63 A C-curve 3-pole position.
