Siemens 5SJ6 Retail line MCB, 2-pole, 25 A, C characteristic, 6 kA breaking capacity, order code 5SJ6225-7RC.
The 6 kA breaking capacity at 230/400 V AC is the standard domestic and light-commercial rating per IEC 60898-1; it safely interrupts a fault up to 6 kA without welding the contacts or cascading upstream. For industrial panels with higher prospective fault current (above 6 kA), you would step to the 5SJ4 or 5SY series with 10 kA or 25 kA ratings.
The 2-pole width (2 modules at 18 mm each) fits standard distribution boards and sub-distribution panels.
The C characteristic trips magnetically at 5 to 10 times the rated current (125–250 A for this 25 A unit), making it suitable for circuits with moderate inrush such as small motors, lighting, and transformers.
This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
The breaking capacity is 6 kA per IEC 60898-1, suitable for standard domestic and light-commercial fault levels.
