The short-time delayed G characteristic (super resistant K variant) tolerates brief leakage pulses from electronics or surge suppressors, so it won't drop out on equipment with normal leakage.
The 16 A rating holds only at 30 °C ambient. In a crowded enclosure at 40 °C the continuous current drops to 15.2 A; at 50 °C it's 14.4 A; at 60 °C it's 13.6 A; at 70 °C it's 12.32 A. Mounting position is unrestricted, so vertical or horizontal DIN-rail orientation does not affect the derating curve.
This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or lead-time number is published here.
The 5SL6550-7BB is a different form factor (single-pole MCB, no residual-current protection) and cannot drop into the same panel without rewiring. The 5SU1354-1LB16 is an RCBO combining overcurrent and earth-leakage protection in one unit; a direct functional replacement would need the same 1P+N, C-curve, 16 A, and short-time delayed G characteristics.
Depth 77 mm, width 36 mm (2 modular units), height 90 mm. Installation depth behind the panel is 70 mm. Weight with packaging is 274 g.
The part carries EN 60898 and IEC 60947-2 ratings, overvoltage category III, pollution degree 2, and IP20 protection (when installed in a distribution board with connected conductors). It is halogen-free and silicon-free. Full RoHS/REACH declarations are available from Siemens documentation.
