The B-curve (3–5× In) means it trips fast on moderate overloads — typical for lighting and general-purpose socket circuits where inrush is low. At 3 width units (54 mm wide, 90 mm tall, 76 mm deep), it snaps onto a standard DIN rail in any mounting position, with IP20 protection once the conductors are connected. The B-curve at 6 A protects wiring and loads that don't see heavy motor-starting surges — think lighting circuits, small appliances, control transformers. The 10 000 mechanical switching cycles are standard for this class; the unit is sealable (tamper-evident) for metering or landlord applications. At 54 mm wide (3 width units), it occupies three 18 mm module spaces. Overvoltage category III means it's rated for fixed-installation distribution boards, not for downstream equipment. No neutral switching — this is a 3-pole device for 3-phase circuits without a switched neutral.","metaTitle":"Siemens 5SL3306-6 SENTRON MCB, 3-pole B-curve 6 A 4.5 kA","metaDescription":"Siemens 5SL3306-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 6 A, 4.5 kA breaking capacity at 400 V AC.
