The IEG1-1REC5-69-.100-21-V magnetic circuit protectors provide low-cost power switching, reliable circuit protection and accurate circuit control. They’re ideal for data processing and business machines, medical instrumentation, broadcast equipment, vending and amusement machines, military applications and wherever precision operation is required. Temperature differences which affect fuses and other thermal devices are not a concern. One important feature of this protector line is a “trip free” action, which means the circuit will trip in the presence of an overload even though the handle is held in the ON position. The delay mechanism senses the fault and the contacts open.
