The IAGNF6-1-73-50.0 is a single-pole, series-trip hydraulic-magnetic circuit protector designed for reliable overcurrent protection and power switching. This device is rated for 50.0 amperes and features a sealed toggle with a silicone rubber seal, making it ideal for harsh environments. It incorporates a DC/60Hz motor start delay curve (Delay 73) and a trip-free mechanism that ensures the circuit opens during an overload, even if the handle is held in the ON position. The protector operates reliably in a wide ambient temperature range from -40°C to +85°C. Its hydraulic-magnetic design provides precise protection unaffected by ambient temperature changes, making it suitable for applications like data processing equipment, medical instrumentation, and military systems.
