The IUGN62-34230-1 is a sealed toggle hydraulic-magnetic circuit protector designed for reliable circuit protection in harsh environments. It features a series trip configuration with a 30A current rating and a long delay (62) curve suitable for 50/60Hz applications, making it tolerant to motor starting and transformer inrush currents. The silicone rubber seal around the toggle handle ensures panel seal integrity, and this trip-free protector operates reliably in ambient temperatures from -40°C to +85°C. Its robust, sealed design makes it ideal for use in military applications, medical instrumentation, and data processing equipment.
