It occupies 4 modular width units (72 mm) on the DIN rail and is IP20 rated with connected conductors — standard for distribution board installation in residential and infrastructure builds. The B-curve trips between 3 and 5 times rated current (96–160 A magnetic release), making it a good fit for resistive and lighting loads where inrush is moderate. The 6 kA breaking capacity at 400 V AC means it can safely interrupt a fault current up to 6 kA without upstream devices needing to clear it — adequate for most residential and light commercial service entrances where the prospective short-circuit current stays below that level. Sealable with a lead seal to prevent tampering — useful for metering or rental subpanels. Supplementary devices (shunt trip, auxiliary contacts) can be added on the right side via the product extension feature.","metaTitle":"Siemens 5SL6432-6 SENTRON MCB, 4P, B Curve, 32 A, 6 kA","metaDescription":"Siemens SENTRON 5SL6432-6 miniature circuit breaker, 4-pole, B-curve, 32 A, 6 kA breaking capacity per EN 60898/IEC 60947-2.

Both share the same 76 mm depth and 90 mm height, so the panel cutout and depth clearance are compatible, but the 4-pole unit occupies one extra modular space. If the panel has a spare MW slot, it fits mechanically; the wiring difference is the fourth pole (neutral or additional phase)."},{"question":"Where can I buy 5SL6432-6 and how is it quoted?","answer":"The 5SL6432-6 is sourced to order through independent distribution.
