Rated voltage goes to 440 V in multi-phase operation.
Width is 18 mm — one modular unit on a standard DIN rail. That means it fits a standard 18 mm-wide slot; no special adapter needed. Mounting position is any, so vertical or horizontal rail orientation works. Temperature derating matters here. At 35 °C ambient the breaker carries its full 1 A rating. At 40 °C it derates to 0.92 A, at 45 °C to 0.88 A, at 50 °C to 0.83 A, and at 55 °C to 0.78 A. The maximum ambient is 75 °C; minimum is -40 °C.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
The D tripping characteristic (per EN 60898) allows a higher magnetic trip threshold — typically 10–20 times the rated current — so it avoids nuisance tripping on motor starts, transformer inrush, or capacitive loads that a B or C curve would catch.
Siemens SENTRON MCBs are designed and tested to EN 60898 and IEC 60947-2 standards. The part carries the CE marking and is suitable for use in industrial control panels per the listed specifications.
