The neutral pole switches with the line — no separate neutral bar needed in the load center. ## D-curve and thermal derating At 0.5 A the instantaneous trip threshold sits between 5 A and 10 A. Rated current is temperature-sensitive: 0.5 A at 30 °C, 0.47 A at 40 °C, 0.46 A at 45 °C, and 0.43 A at 55 °C. Rated short-circuit capacity is 10 kA. Energy limitation class 3 means it lets through less let-through energy (I²t) than class 1 or 2 breakers. Dimensions: 36 mm wide (2 MW), 90 mm tall, 76 mm deep, with 70 mm installation depth into the panel. Sealable, halogen-free, silicon-free, with touch protection on the line-side terminals. Overvoltage category III, pollution degree 2 — standard for fixed-installation mains distribution.","metaTitle":"Siemens 5SL4505-8 SENTRON MCB, 2-Pole D-Curve 0.5A 10kA","metaDescription":"Siemens 5SL4505-8 SENTRON miniature circuit breaker, 1P+N, D-curve, 0.5 A, 10 kA breaking capacity per IEC/EN 60898.

The difference is the curve and rating: the 5SL4363-7 is a B-curve at a higher current, while the 5SL4505-8 is a D-curve at 0.5 A.
