It occupies a single modular width (18 mm) on DIN rail and installs at 55 mm depth — shallower than the standard 70 mm SENTRON units, which matters when panel depth is tight. Snap-on DIN rail mounting, 1 MW slot. IP20 finger-safe with conductors connected; no neutral switching on this pole. C-curve means magnetic trip between 5× and 10× rated current (10–20 A for this 2 A unit), suited for moderate inrush loads like small contactors or control transformers. Derate at elevated panel temperatures: 1.85 A at 40 °C, 1.6 A at 60 °C.","metaTitle":"SENTRON 5SQ2170-2YA02 Miniature Circuit Breaker, 1-Pole C 2A","metaDescription":"Siemens SENTRON 5SQ2170-2YA02 miniature circuit breaker, 1-pole, C-curve 2A, 3kA breaking capacity per EN 60898, 240 V AC.
