Overview
The Westinghouse FH83 is a Type FH thermal overload heater element designed for use in A200 series thermal overload relays, magnetic motor starters, and motor control systems. With a current rating of 52-56 amps, the FH83 provides reliable overload protection for motors operating in this amperage range. This component is compatible with Sizes 3 and 4 A200 starters and is essential for preventing motor damage from sustained overcurrent conditions.
