Eaton's Freedom starters and contactors feature a compact, space-saving design, using state-of-the-art technology and the latest in high strength, impact and temperature resistant insulating materials. In addition to the bimetallic overload, Eaton also offers a series of electronic overload relay (C440) available as a standalone unit and assembled with Freedom contactor. These adjustable bimetallic ambient compensated contactors are designed for use with CE or CN non-reversing and reversing contactors. They have interchangeable heater packs and are available in four sizes for overload protection up to 900 hp, reducing the number of different contactor/overload relay combinations that have to be stocked. They also feature a full line of snap-on accessories common to both IEC and NEMA devices.
