Product details

Siemens 5SJ6516-6 — SENTRON 1P+N MCB, B Curve, 16 A

The Siemens 5SJ6516-6 is a SENTRON 5SJ6 miniature circuit breaker with a 1P+N pole configuration, B tripping characteristic, and a 16 A rated current at 240 V AC. Rated for 50 Hz AC supply, the breaker accepts solid and stranded conductors from 0.75 to 25 mm², with a 70 mm installation depth and IP20 protection (finger-safe with connected conductors). Vibration resistance per IEC 60068-2-6 is 50 m/s² at 25 to 150 Hz and 60 m/s² at 10 to 150 Hz. The neutral pole switches (1P+N design), and the supply cord position is unrestricted.

Panel Integration

Any mounting position is allowed.

Frequently asked questions

Where can I buy 5SJ6516-6 and get current pricing?

The 5SJ6516-6 is available to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

What is the closest functional second-source for 5SJ6516-6?

The 5SL6016-7KL is a SENTRON 1P+N MCB with the same 16 A rating and 6 kA breaking capacity, but with a C curve instead of B. The 5SL4120-7CC is a 1P, 20 A, C-curve unit with a 10 kA breaking capacity — different pole count and rating. Neither is a direct form-fit-function drop-in; verify coordination and selectivity for your application.

What conductor sizes does 5SJ6516-6 accept?

It accepts solid and stranded conductors from 0.75 to 25 mm².

Is 5SJ6516-6 sealable?

Yes, the breaker is sealable for tamper-evident applications.

Will 5SJ6516-6 drop into a panel specified around 5SL4120-7CC?

The 5SJ6516-6 is 2 width units (36 mm) vs 1 width unit (18 mm) for the 5SL4120-7CC, so it requires more DIN rail space. Both mount on standard DIN rail with 70 mm installation depth, but the pole count (1P+N vs 1P), rating (16 A vs 20 A), and tripping curve (B vs C) differ. Rewiring and coordination review are needed.
