AR2.24

50°C to 450°C [122°F to 842°F] bimetallic thermal overload relay block heater element. Calibrated to match a specific 2.24 Amp internal trip threshold profile to protect heavy three-phase industrial blower motors from burnout conditions. Installed within centralized magnetic motor starters, industrial fan ventilation control tracks, and factory furnace pump modules. Industry-standard direct replacements and cross-manufacturers include Allen-Bradley AR2.24, Square D (Schneider) thermal heaters, General Electric overload elements, and Westinghouse Type W components.
