Siemens 5SJ6406-6RC, MCB Retail line, 4-pole, 6kA, 6A, B characteristic.
The B-curve (3–5× In) makes it a standard choice for general-purpose loads like lighting and socket outlets where inrush is modest.
The 4-pole format handles three-phase plus neutral circuits — typical for three-phase lighting or small motor feeder protection in a single enclosure.
The 5SJ6406-6RC has a 6kA breaking capacity, meaning it can safely interrupt short-circuit faults up to 6,000 amps at its rated voltage.
The 5SJ6406-6RC is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
The B-characteristic means the MCB trips at 3 to 5 times its rated current (18–30 A for this 6A unit), making it suitable for circuits with low inrush currents such as lighting and socket outlets.
