The IUGNF66-33485-5 is a two-pole hydraulic-magnetic circuit protector from the sealed toggle IUGN family. It features a trip-free mechanism that ensures circuit interruption during an overload, even if the handle is held in the ON position. The silicone rubber sealed toggle with bushing mounting provides panel seal integrity, making it ideal for harsh environments. This protector is rated for up to 80Vdc or 240Vac at 50/60Hz and operates reliably across a wide temperature range from -40°C to +85°C. Its robust design is ideal for applications such as data processing equipment, medical instrumentation, military systems, and broadcast equipment where precision operation is required.
