Product details

IP20 with conductors connected; overvoltage category III, pollution degree 2. Mount in any position, sealable for tamper-proofing. Halogen-free and silicon-free construction, so it's safe for clean-room or food-bev environments where outgassing matters.

Thermal derating and service life

Rated 2 A at 30 °C ambient; derates to 1.92 A at 40 °C, 1.88 A at 45 °C, and 1.79 A at 55 °C. If the panel runs hot (e.g., enclosed switchgear near a furnace line), size the load accordingly. Ambient range -40 to 75 °C covers most outdoor enclosures in temperate climates.
