For a panel with sustained internal temperatures near 50 °C — common in a furnace control cabinet or a crowded enclosure — the effective continuous current is about 33 A, not the nameplate 40 A. The operating temperature range spans -40 to 75 °C, with humidity limits of 95 % RH up to 55 °C and 55 % RH up to 70 °C.","metaTitle":"Siemens 5SY6140-7CC SENTRON MCB, 1P C 40 A 6 kA","metaDescription":"Siemens SENTRON 5SY6140-7CC miniature circuit breaker, 1-pole C-curve 40 A, 6 kA per EN 60898, 440 V AC.
