What the ratings mean for fit
The 5SL6332-8CC is a SENTRON miniature circuit breaker — 3-pole, D-curve, rated 32 A at 400 V AC with a 6 kA breaking capacity per EN 60898. The D characteristic means it tolerates high inrush currents (5–10× rated), so it's the right call for motor, transformer, or lighting ballast circuits where a B or C curve would nuisance-trip on startup. At 30 °C it carries the full 32 A; at 40 °C it derates to 30.18 A, at 50 °C to 28.24 A — so if your panel ambient runs hot, size the load accordingly or move up a frame. The 6 kA SCCR at 400 V covers most residential and light commercial service-entrance faults; if your available fault current is higher, you'll need a current-limiting upstream device.
Panel integration and mounting
Snaps onto DIN rail, any mounting position — no orientation restrictions. Occupies 3 modular width units (54 mm wide), with an installation depth of 70 mm and overall depth of 76 mm. The IP20 rating (with connected conductors) is standard for enclosed distribution boards; not for wet or washdown locations. Touch protection is built in, and the unit is sealable — useful for utility or metering applications where tamper evidence matters. Vibration resistance is rated at 50 m/s² over 25 to 150 Hz per IEC 60068-2-6, so it holds up on machine-mounted subpanels.
Environmental and compliance notes
Halogen-free and silicon-free construction — relevant for clean-room, semiconductor, or high-reliability installations where outgassing or contamination is a concern. Rated for pollution degree 2 and overvoltage category III, which covers fixed-installation distribution boards. Operating temperature range spans -40 °C to 75 °C, so it's fine in unheated enclosures or outdoor-rated cabinets as long as they stay dry. The product designation per EN 61346-2 and IEC 81346-2 is 'F' — that's the standard function code for circuit protection.
