The E tripping characteristic is designed for selective coordination in residential and infrastructure distribution boards — it holds through motor inrush and transformer magnetizing currents without nuisance tripping, then clears hard faults fast. Mounts directly onto a 40-mm busbar system per DIN 43870 Part 2 — the standard meter-panel grid found across European residential and light-commercial infrastructure. Occupies 1.5 width units, so it fits a compact footprint. Infeed is via the box terminal at the bottom; outgoing feeder uses a spring-loaded terminal. The enclosure depth is 76.3 mm; overall depth including terminals is 89.5 mm — check your cabinet clearance if using deep gland plates. ## Environmental and mechanical ruggedness Shock-rated to 30 g (11 ms duration, 3 impacts) and vibration-tested per IEC 60068-2-6 at 2 g, 20 cycles from 5 to 150 Hz. Overvoltage category IV, surge voltage resistance 6 kV — suitable for utility-side installation where lightning-induced surges are a concern.","metaTitle":"Siemens 5SP3735-2KK01 SENTRON MCB, 1P 35A, 25kA, Char E","metaDescription":"Siemens 5SP3735-2KK01 SENTRON miniature circuit breaker, 1-pole, 35 A, 25 kA breaking capacity, tripping characteristic E.
