At 25 A and 230 V AC, this MCB handles a nominal load of roughly 5.75 kVA on a single-phase circuit. The B characteristic means it will hold through a short motor start or capacitor charge but trip promptly on a hard fault — it is not suited for high-inrush loads like large transformers or motor drives (those need C or D curves). The 1P+N format saves one DIN width unit (36 mm total) compared to a 2-pole breaker, but note the neutral pole is switched only, not protected — the overcurrent protection is on the phase pole alone. Wire range accepts 0.75 to 25 mm² solid or stranded, and the screw terminals require 2.5 to 3 N·m torque — consistent with standard panel-building practice for this conductor size. Installation depth is 70 mm; total depth with the housing is 76 mm — enough clearance for a standard distribution board with a 100 mm back panel.","metaTitle":"Siemens 5SL6525-6BB SENTRON MCB, 25 A, 1P+N, B Curve, 6 kA","metaDescription":"Siemens 5SL6525-6BB SENTRON miniature circuit breaker, 25 A, 1P+N, B tripping characteristic, 6 kA breaking capacity per EN 60898.
