What it is and what it does
The Siemens SENTRON 5SL6432-7RC is a 4-pole miniature circuit breaker (MCB) from the 5SL6 series, rated 32 A at 415 V AC with a C tripping characteristic and a 7.5 kA breaking capacity per EN 60898. The C curve means it tolerates moderate inrush — typical for motor, transformer, or lighting loads in residential and light commercial infrastructure — without nuisance tripping on startup, while still clearing a hard fault fast enough to protect downstream wiring.
Panel fit and mounting
Snaps onto standard DIN rail; the 72 mm width (4 width units) and 76 mm depth leave room for adjacent breakers in a crowded enclosure. Mounting position is any, so it works in vertical or horizontal busbar layouts. IP20 with connected conductors means it's for enclosed panels only — no washdown exposure.
Lifecycle and sourcing reality
Current lifecycle stage per the manufacturer — no phase-out or NRND flag on this code. That means it's still a standard BOM line, not a last-time-buy scavenger hunt. Sourced to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
