Rated 1 A at 30 °C ambient, the 5SQ2170-2YA01 derates to 0.93 A at 40 °C, 0.9 A at 45 °C, 0.87 A at 50 °C, 0.84 A at 55 °C, and 0.8 A at 60 °C. That thermal curve matters when the breaker shares a crowded enclosure with heat-generating loads — a 40 °C panel ambient drops the usable current by 7 %, and a 60 °C environment cuts it by 20 %. Current production. Active catalog item in the SENTRON 5SQ series. ## Integration notes Snap-on mounting to DIN rail. Pollution degree 3, overvoltage category 3. IP20 with connected conductors. No neutral conductor switching.","metaTitle":"Siemens 5SQ2170-2YA01 SENTRON MCB, 1-Pole C 1A, 3 kA","metaDescription":"Siemens SENTRON 5SQ2170-2YA01 miniature circuit breaker, 1-pole, C-curve 1 A, 3 kA breaking capacity per EN 60898, 240 V AC.
