Product details

The Siemens 5SL4150-8 is a 1-pole SENTRON miniature circuit breaker with a D tripping characteristic, rated 50 A at 30 °C and 400 V AC. That's the spec that decides fit for inductive circuits.

Derating and thermal reality

At 40 °C it's 46.19 A; at 45 °C, 44 A; at 55 °C, 39.81 A. That's the number to spec against for continuous load, not the 30 °C headline.

Mounting position is unrestricted — can go horizontal or vertical. Halogen-free and silicon-free construction, sealable for tamper-evident applications.
