It is not intended for motor-starting duty where higher inrush would nuisance-trip a B-curve device. ## Fit and footprint Mounting position is unrestricted. The IP20 rating applies only with conductors connected — meaning the terminals are finger-safe once wired, but the breaker itself is not sealed against dust ingress in an unpopulated panel. Sealable design allows a lockout tagout hasp on the toggle. ## Electrical environment The single-pole unit switches the line conductor only; neutral must be bonded separately. Power dissipation is 3.1 W per pole at rated current — negligible for a single unit but worth summing in a densely populated sub-distribution board.","metaTitle":"Siemens 5SL1132-6MB SENTRON MCB, 1P B-Curve 32A 3kA","metaDescription":"Siemens 5SL1132-6MB SENTRON miniature circuit breaker, 1-pole, B characteristic, 32 A rated current, 3 kA breaking capacity per IEC 60947-2.

That is the maximum prospective fault current it can safely interrupt at 230/400 V AC without welding its contacts or rupturing the arc chamber."},{"question":"What does the B-curve mean on this breaker?","answer":"The B characteristic trips magnetically at 3 to 5 times rated current (96–160 A for this 32 A unit). That makes it appropriate for resistive loads and general-purpose circuits where inrush is low — lighting, socket outlets, small appliances — not for motor or transformer circuits that draw a higher starting surge."},{"question":"Where can I buy the 5SL1132-6MB?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quotation."},{"question":"Will the 5SL1132-6MB drop into a panel designed for a 5SL4363-7?","answer":"No — the 5SL4363-7 is a 3-pole unit (54 mm wide, 3 MW) with a C-curve and 10 kA breaking capacity. The 5SL1132-6MB is a single-pole (18 mm, 1 MW) B-curve device. They share the same depth (76 mm) and DIN-rail mounting, but the pole count, width, characteristic, and interrupting rating are all different. A panel wired for the 3-pole unit would need rewiring to accept this single-pole breaker."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL1132-6MB","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/5SL1132-6MB when reusing this data.
