The 40 A rating holds at 35 °C; at 40 °C ambient it derates to 36.76 A, at 45 °C to 35 A, and at 50 °C to 33.16 A. 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.
Rated 6 kA at AC per EN 60898, with a rated voltage of 440 V AC.
The MCB carries the SENTRON brand and is designed to EN 60898 and IEC 61346-2 / 81346-2 (function code F). It is halogen-free and silicon-free. For specific RoHS, REACH, UL, or IEC declarations, request the manufacturer's compliance pack with your RFQ.
