Integrator note – 5SL6432-6CC
The Siemens 5SL6432-6CC is a 4-pole miniature circuit breaker from the SENTRON 5SL6CC family, rated 32 A at 400 V AC with a B tripping characteristic and 6 kA breaking capacity per EN 60898. Accepts solid or stranded conductors from 0.75 to 25 mm² at the screw terminals, tightened to 2.5–3 N·m. No neutral conductor switching — this is a 4P device, not a 3P+N. Rated for 50 Hz only; maximum operating voltage in multi-phase operation is 440 V AC.
Coordination & compliance
Energy limiting class 3; overvoltage category III. Sealable, halogen-free, silicon-free. Touch protection on the terminals. Suitable for residential buildings and infrastructure per the manufacturer's designation.
Snap-on DIN rail mount, any position. Four width units (72 mm) occupy standard panel space. Screw terminals accept 0.75–25 mm² solid or stranded; tighten to 2.5–3 N·m. Strip length not specified — follow standard practice for the terminal cross-section. No neutral pole switching; confirm the downstream neutral bar is separate.
