The Siemens 5SL7132-8RC is a 1-pole miniature circuit breaker rated at 240/415 V with a D tripping curve, 32 A rated current, and a 15 kA breaking capacity.
For an MRO planner stocking a panel: this is a standard DIN-rail MCB from the Siemens 5SL series, a common fast mover across commercial and light industrial sites. Keep it on the shelf if your BOM calls for a D-curve 32 A single-pole unit.
The 1-pole form factor takes one module width (roughly 18 mm), so it fits tight enclosures where space is at a premium. Rated for 240/415 V systems — typically used on a single-phase branch circuit fed from a 3-phase 415/240 V supply, with the neutral bar common to the panel.
