The Siemens Betagard 5SL7206-3RC is a 2-pole miniature circuit breaker (MCB) with a K tripping characteristic, rated 6 A at 415 V AC and a breaking capacity of 15 kA per EN 60898.
The IP20 rating applies with connected conductors; the housing is sealable and halogen-free, suitable for clean-room or low-smoke environments.
Thermal derating & ratings
Rated 6 A at 50 °C ambient; derate to 5.7 A at 60 °C. At 30 °C the breaker handles 6.5 A continuous. The K characteristic means magnetic trip at 8–12× In, so it holds through motor inrush but clears fast on hard shorts. Overvoltage category III, pollution degree 2 — standard for distribution panels.
