Overview
The Allen-Bradley W62 is a thermal overload relay heater element engineered for reliable motor overload protection in industrial automation systems. Built with eutectic alloy construction, this NEMA-rated heater element delivers Class 20 protection and is designed for use with Bulletin 500 line starters, magnetic motor starters, and motor control systems. The W62 is the industry-standard choice for drop-in replacement and new installations where consistent thermal overload protection is required.
