Rated 2 A at 35 °C, derated to 1.9 A at 40 °C, 1.85 A at 45 °C, 1.8 A at 50 °C, 1.75 A at 55 °C, and 1.7 A at 60 °C. In a warm panel near 50 °C, you lose 10 % of the rated current — size accordingly.
Designed for railway applications per the product designation, and suitable for mechanical engineering and industry.
This part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote — availability and current pricing are confirmed at quote time.
The depth is 76 mm. Installation depth is 70 mm, so it needs about 6 mm of clearance behind the DIN rail for wiring.
Width is 18 mm, which is 1 modular width unit (1 MWU). It occupies one standard DIN-rail slot.
Both are 1-pole SENTRON MCBs with the same 18 mm width and DIN-rail mount. The 5SY4101-7CV is a different rating and curve — verify the load current and trip characteristic before swapping. The footprint and terminal arrangement are the same.
The part is designed to EN 60898 and IEC 60947-2. It is halogen-free and silicon-free. For specific RoHS/REACH/UL declarations, request the manufacturer's compliance documentation at quote time.
