The Siemens SENTRON 5SJ6232-6RC is a 2-pole miniature circuit breaker rated 32 A with a B tripping characteristic and a 6 kA breaking capacity per EN 60898. It occupies 2 modular width units (36 mm) on a DIN rail.
What the ratings mean for fit
The B characteristic means the magnetic trip activates at 3 to 5 times rated current — suited for resistive and general-purpose loads where inrush is modest. At 32 A and 6 kA SCCR per EN 60898, it protects branch circuits in retail or light commercial distribution boards where the prospective fault current stays under 6 kA. Rated for single-phase up to 250 V AC and multi-phase up to 440 V AC; also rated 72 V DC maximum, so it can serve DC control circuits within that limit. The 2-pole design switches both line and neutral simultaneously, with no neutral conductor switching component — it's a double-pole overcurrent device, not a switched-neutral accessory.
Where it goes
Snaps onto DIN rail in any mounting position; installation depth is 70 mm behind the panel face. The IP20 rating with connected conductors means it's intended for enclosed distribution boards, not wet or washdown environments. Rated for pollution degree 2 and overvoltage category III, which covers fixed-installation distribution panels downstream of the main service entrance. Sealable design allows the installer to lock the toggle position — useful for retail or public-access panels where unauthorized reset must be prevented.
