It's designed for residential and infrastructure meter panels, mounting on a 40-mm busbar system per DIN 43870 Part 2. The E curve means it's tailored for feeder protection where moderate inrush tolerance is needed — think main incomers or distribution subfeeds in building installations. At 63 A, this breaker handles a substantial residential or light commercial main feed — enough for a multi-unit panel or a large single-family service. Overvoltage category IV (6 kV surge rating) confirms it's rated for the utility-side interface, not just downstream branch circuits. Insulation voltage is 690 V, giving headroom for 400 V line-to-line applications if needed. Physical fit: 89.5 mm deep, 151.3 mm high, occupying 1.5 width units on the busbar. The depth includes the enclosure at 76.3 mm plus the spring-loaded outgoing terminal. Sealable and lockable (locking slide with wire seal, cable ties, Antilux) for utility or authority sealing. ## Integration notes Mounts on a 40-mm busbar system per DIN 43870 Part 2 — standard for European meter panels. Infeed is via box terminal at the bottom (stipulated by installation in the lower section of the meter panel). Outgoing feeder uses a spring-loaded terminal, no screw torque to manage. Switch position indicator shows OFF = green, ON = red. Shock-rated to 30 g (3 impacts, 11 ms duration) and vibration-rated to 2 g per IEC 60068-2-6 — robust for transport and utility environment.","metaTitle":"Siemens 5SP3763-2KK01 SENTRON MCB, 1-pole, 63 A, E-curve, 25","metaDescription":"Siemens SENTRON 5SP3763-2KK01 main miniature circuit breaker, 1-pole, 63 A, E tripping characteristic, 25 kA breaking capacity per EN 60898.
