The DC voltage rating of 72 V per pole means the two poles are series-connected internally to achieve the 250 V DC system voltage — this is not a 2-pole AC breaker pressed into DC service, but a purpose-designed DC unit. At 36 mm wide (2 modular width units) and 76 mm deep, this breaker occupies two standard 18 mm DIN-rail slots. IP20 with connected conductors is the norm for a DIN-rail enclosure; keep the panel door closed or use a distribution board cover. Halogen-free and silicon-free construction, so it's safe for use in clean-room adjacent panels or areas where outgassing from a fault could contaminate optics or contacts. The sealable design lets you lock the toggle in the off position with a padlock — required for lockout/tagout on DC circuits where no upstream isolator exists.","metaTitle":"Siemens 5SL5220-6CC SENTRON MCB, 2P DC 250V B20 10kA","metaDescription":"Siemens 5SL5220-6CC SENTRON miniature circuit breaker, 2-pole DC, 250V, 20A, B-curve, 10kA breaking capacity.

The 5SL5220-6CC is 36 mm wide (2 modular units) versus the 18 mm width of the 5SL6132-6MB. The depth and height are identical at 76 mm and 90 mm, so the DIN-rail clip and enclosure depth are compatible, but you need an extra 18 mm of DIN-rail space per breaker."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL5220-6CC","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/5SL5220-6CC when reusing this data.
