The B-curve at 40 A trips between 3 and 5 times rated current (120–200 A magnetic release), sized for resistive or lightly inductive loads where inrush stays moderate — think lighting banks, small heaters, or control transformers.","metaTitle":"Siemens 5SU1354-6KV40 RCBO Type A 30mA 10kA 1+N B 40A","metaDescription":"Siemens 5SU1354-6KV40 FI/LS protector Type A, 30mA, 10kA, 1+N-pole B 40A.
