• Cast iron frame and end shields for exceptional structural integrity, with UL approved condensation/breather drains on 404T to 449T frames
• A unique rotor bar design provides improved efficiency while larger bars and end rings reduce resistance for lower rotor losses
• Each die-cast aluminum rotor assembly is dynamically balanced for extended bearing life and includes a high strength carbon steel (C1045) shaft for maximum rotor performance
• Manufactured with premium electrical grade steel laminations and copper electrical magnet wire to reduce losses and improved efficiencies
• A unique stator core design lowers flux density while increasing cooling capacity
• Large conductor cross section reduces resistance and lowers stator losses
• Proprietary class F, non-hygroscopic insulation system with NEMA class B temperature rise, provides an extra margin of thermal life
• Varnish system application ensures maximum wire penetration to provide protection from moisture, corrosion and electrical surges
• Two series connected normally closed class B thermostats are supplied as standard
• A bi-directional, non-sparking fan is locked and keyed to the shaft
• Its design reduces windage losses, improves airflow, reduces noise and provides dependable cooling
• Cast iron fan covers are provided on all frame sizes
• Regreasable, oversized single shielded bearings with cast iron inner caps
• Alemite® grease fittings on the inlets and pipe plugs on the relief ports for ease of routine maintenance
• Specially formulated, high temperature, polyurea based grease
• Oversized cast iron construction that is larger than industry standards, non-wicking, clearly and permanently marked leads
• Cast iron construction, zinc plated hardware, epoxy enamel paint and stainless steel nameplate resist rust and corrosion
• RAL7030 standard stone gray paint finish
• Thermostats, Klixon type, normally closed
