What this MCB does on the rail
The Siemens 5SL6432-7CC is a 4-pole SENTRON miniature circuit breaker rated 32 A at 400 V AC with a C tripping curve and a 6 kA breaking capacity per EN 60898. That C-curve means it holds through moderate inrush — motorized loads like small pumps or fan coils — and trips fast on a hard short. Four poles in a 4-module-wide housing (72 mm wide, 90 mm tall, 76 mm deep) with a 70 mm installation depth. Mounts in any position on standard DIN rail.
Integration notes
Sealable housing (tamper-evident sticker or wire seal) for metering or common-area panels where unauthorized switching needs to be visible. That covers most indoor and sheltered outdoor enclosures.
