The Siemens 5SL6432-8CC is a SENTRON 5SL6-series miniature circuit breaker — 4-pole, D-curve, rated 32 A at 400 V AC with a 6 kA breaking capacity per EN 60898. It's designed for residential and infrastructure distribution boards — think apartment risers, lighting panels, or small commercial sub-distribution — where you need a 4-pole disconnect in a 4-module-wide footprint (72 mm).
At 50 Hz, the D-curve trips magnetically between 10× and 20× In — so for a 32 A breaker, instantaneous trip occurs between 320 A and 640 A. That's the window that avoids nuisance trips on motor start but still clears a bolted fault fast. Terminals accept solid or stranded copper from 0.75 mm² up to 25 mm² — covers everything from 1.5 mm² lighting circuits to 10 mm² feeders. The housing is IP20 with conductors connected, so it's for enclosed distribution boards only, not wet locations.
Snap-on DIN rail mount, any position. The 4-module width (72 mm) and 76 mm depth fit standard 18 mm pitch distribution boards. The breaker is sealable — useful for utility metering or tamper-proof installations. Terminal covers provide touch protection per the product feature listing.
