The 16 A rating at 30 °C is the baseline; at 40 °C it derates to 15.2 A, and at 70 °C it drops to 12.32 A. If this RCBO sits in a crowded enclosure where ambient hits 50 °C, expect 14.4 A continuous — plan the load accordingly. The B curve means magnetic trip at 3–5× In (48–80 A), so it's a fit for lighting circuits, socket outlets, and general-purpose distribution rather than motor starts that draw 6–10× FLA. The design carries 'short-time delayed G, super resistant K' — the G characteristic introduces a deliberate delay to tolerate brief surge currents (like capacitor inrush or transformer magnetising), while the K variant is built for higher mechanical and thermal endurance in frequent-switching applications. This isn't a generic domestic RCBO; it's rated for industrial panel duty where nuisance tripping costs line time. The 77 mm depth (70 mm installation depth) fits standard 18 mm-module distribution boards with room for wiring.","metaTitle":"Siemens 5SU1354-6LB16 SENTRON RCBO, 16 A, Type A, 10 kA","metaDescription":"Siemens 5SU1354-6LB16 SENTRON RCBO, 2-pole 1P+N, 16 A rated, Type A residual current, B curve, 10 kA (EN 60898) / 20 kA (IEC 60947-2).
