Energy limiting class 3 means the breaker restricts the let-through energy (I²t) to a defined low level during a short circuit, which helps protect downstream components and reduces arc-flash hazard. The AC/DC voltage type means the same unit can be applied on a DC control circuit up to the rated voltage — though the 3 kA breaking capacity is only confirmed at AC; DC derating applies per the manufacturer's curves. ## Integration note: panel fit and wiring Snap-on DIN rail mounting, 1 width unit, 55 mm depth — fits any standard 35 mm rail enclosure. No neutral switching on this 1-pole version (the neutral bar passes through or lands on a separate terminal block). The C-curve at 13 A is a common choice for lighting circuits, small fan motors, or control transformer primaries in a conveyor zone panel. If your BOM calls for a higher breaking capacity — say 10 kA for a service-entrance position — the 5SY4140-7 sibling carries that rating but at a 70 mm depth, so it won't drop into the same DIN rail footprint without checking the enclosure depth.","metaTitle":"SENTRON 5SQ2170-0KA13 MCB, 1-Pole C-Curve 13A, 3kA","metaDescription":"SENTRON 5SQ2170-0KA13 miniature circuit breaker, 1-pole, C-curve, 13A rated at 240V AC. 3kA breaking capacity per EN 60898/IEC 60947-2.
