Rated 1 A at 35 °C; derates to 0.85 A at 60 °C. The full operating range spans -40 °C to 75 °C, with humidity limits of 95% RH up to 55 °C, tapering to 35% RH at 75 °C. In a warm panel (say 50 °C internal ambient), expect 0.9 A continuous — factor that into the load schedule. Halogen-free and silicon-free construction avoids outgassing issues in sealed enclosures.
Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. Halogen-free and silicon-free construction.
10 kA per EN 60898 and 35 kA per IEC 60947-2.
Both share the same SENTRON 5SY4 platform, 3-pole B-curve, 2 MW width, and similar terminal layout — mechanical fit is identical. The difference is the 5SY4301-7CV carries a different rating; verify the load current before substitution.
