Product details

Siemens SENTRON 5SJ6232-7 — 2-pole C-curve MCB, 32 A, 6 kA

Rated 32 A continuous at 400 V AC, this breaker handles branch circuits feeding multiple loads up to that current. Insulation voltage is rated 440 V AC, giving headroom above the 400 V supply. The 2-pole construction switches both phase and neutral (or two phases) simultaneously, which is required for 2-phase loads or where full isolation is specified. The C-curve characteristic (5–10× In) suits loads with moderate inrush: small motors, pumps, compressors, banks of LED drivers, and general-purpose lighting. For purely resistive loads or long cable runs where nuisance tripping is a concern, a B-curve sibling would be a better fit.

Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 10–150 Hz per IEC 60068-2-6 — suitable for installation on machinery or in mobile equipment. Rated for 20 000 mechanical switching cycles typical, which is adequate for most branch-circuit applications where the breaker is operated infrequently.

Frequently asked questions

What is the breaking capacity of 5SJ6232-7?

6 kA per EN 60898 and also 6 kA per IEC 60947-2, at 400 V AC.

What is the difference between 5SJ6232-7 and 5SJ6220-6?

Both are 2-pole SENTRON MCBs with the same 6 kA breaking capacity, 400 V AC rating, and physical footprint. The 5SJ6232-7 is a C-curve rated 32 A; the 5SJ6220-6 is a B-curve rated 20 A. The C-curve handles higher inrush (motor/lighting loads), while the B-curve trips faster on lower overcurrents (resistive/cable protection). They are mechanically interchangeable in the same DIN-rail panel.

Where can I buy 5SJ6232-7?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance documentation does Siemens provide for 5SJ6232-7?

The breaker carries approvals per EN 60898 and IEC 60947-2, and is halogen-free and silicon-free. Standard Siemens documentation includes CE declaration, RoHS, and REACH compliance data — request these with your RFQ.
