It is designed for DC circuits in residential buildings and infrastructure applications, such as solar combiner boxes, battery storage branch protection, or DC distribution panels. The 10 kA breaking capacity at 220 VDC means it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream — critical for coordination in a DC string where fault currents can be sustained by multiple parallel sources. ## What the ratings mean for fit The C-curve (tripping characteristic class C) means the magnetic trip activates at 5 to 10 times rated current — suited for loads with moderate inrush, like DC-DC converters, contactor coils, or small motor drives. At 63 A and 220 VDC, this breaker handles the full current of a typical residential solar string inverter or a battery bank branch. The 1-pole design (single pole switched) is correct for ungrounded DC systems where only the positive leg needs overcurrent protection; the negative leg is often left solid or fused separately. The IP20 rating applies only with connected conductors — the breaker itself is not sealed against dust ingress, so it belongs inside a panel or enclosure, not in a wet location. ## Panel integration notes Snaps onto standard 35 mm DIN rail. The 18 mm width (1 modular unit) and 76 mm depth fit standard distribution board cutouts. Installation depth is 70 mm behind the panel surface. Mounting position is any orientation. The breaker is sealable (can be locked in OFF position with a padlock hasp) and accepts supplementary devices (auxiliary contacts, shunt trips, alarm switches) via the accessory slot on the right side. The terminals accept copper conductors; the IP20 protection holds only when conductors are connected — keep the panel door closed during operation.","metaTitle":"Siemens 5SL5163-7RC SENTRON MCB, 1P C63 220 VDC","metaDescription":"Siemens 5SL5163-7RC SENTRON miniature circuit breaker, 1-pole C-curve, 63 A, 220 VDC, 10 kA.

The physical footprint is identical, so it fits the same panel cutout and rail slot without mechanical modification. However, verify the electrical ratings: the 5SL5163-7RC is a 63 A DC-rated breaker (220 VDC), while the 5SY6006-7 is a 6 A AC-rated unit (250 VAC) — they are not electrically interchangeable unless the circuit matches those ratings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL5163-7RC","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SL5163-7RC when reusing this data.
