The Siemens 5SL6532-7 is a SENTRON miniature circuit breaker — single-pole plus neutral, C-curve, rated 32 A at 230 V AC. That 6 kA breaking capacity (per EN 60898 and IEC 60947-2) is what decides fit: it'll clear a fault up to 6 kA without welding its contacts, which covers most residential and light commercial service entrances where the prospective short-circuit current stays under that threshold.
Panel fit and deployment context
Two modular width units (36 mm wide, 90 mm tall, 76 mm deep with 70 mm installation depth) snap onto standard DIN rail. The 1P+N design switches the phase and switches the neutral, but the neutral pole is not protected; it's a switched neutral, common in single-phase final subcircuits where you want isolation on both conductors.
Sealable, halogen-free, silicon-free — relevant for installations that require low-smoke, zero-halogen materials or where silicone contamination could affect downstream equipment.
