The Siemens 5SJ6501-7 is a SENTRON 5SJ6 miniature circuit breaker rated 1 A with a C tripping characteristic, 1P+N pole configuration, and 6 kA breaking capacity per EN 60898 and IEC 60947-2. The 1P+N pole design switches the line and switches the neutral, but the neutral pole does not have overcurrent protection — it's a switched neutral for isolation, not a second protected pole.

Frequently asked questions
What wire sizes does 5SJ6501-7 accept?
Solid conductors from 0.75 mm² to 25 mm², and stranded conductors from 0.75 mm² to 25 mm².
Will 5SJ6501-7 drop into a panel specified around 5SL4120-7CC?
Not without rewiring. The 5SJ6501-7 is a 1P+N (2-pole) breaker occupying 2 width units, while the 5SL4120-7CC is a single-pole (1P) breaker in 1 width unit — the footprint and neutral switching differ.
