Selection & installation notes
- The current ranges are manufacturer selection references, not intrinsic ampere ratings of a heat sink. Verify relay losses, interface resistance, heat-sink thermal resistance, ambient and maximum junction temperature.
- No numerical thermal-resistance or power-dissipation curve is provided in this product record. Do not assume the reference current is available in a sealed cabinet or at85 °C.
- Keep convection channels vertical and unobstructed. Use the relay manufacturer’s flatness, thermal-interface and fastening instructions.
- The045/075 suffix is profile height; overall heights including mounting hardware are49/79 mm. Confirm clearance for relay, terminals and wiring.
