Type A means it detects sinusoidal AC fault currents plus pulsating DC fault currents — the standard for circuits feeding electronic loads like VFDs, switched-mode power supplies, and lighting ballasts that generate half-wave rectified leakage. Rated short-circuit current withstand is 10 kA, and the part carries a 1 kA surge current resistance. The 2-pole body takes 2 width units on DIN rail, with a 55 mm installation depth. ## Thermal derating — the real ampacity Full 40 A rating holds at ambient up to 45 °C. Above that, derate linearly: 38.4 A at 50 °C, 36.8 A at 55 °C, 35.2 A at 60 °C, 33.6 A at 65 °C, and 32 A at 70 °C.","metaTitle":"Siemens 5SM1614-6 SENTRON RCCB, 40A 300mA Type A, 2-pole","metaDescription":"Siemens 5SM1614-6 SENTRON RCCB, 40A rated, 300mA Type A residual current, 2-pole, 10kA SCCR.
