Eaton FH80 Overload Relay Heater Element, A200 Series

Overload Relay Heater Element for Reliable Motor Protection

The Eaton FH80 is a thermal overload relay heater designed for A200 and B100 series starters, providing dependable motor protection by responding accurately to overcurrent conditions. Built to meet strict performance requirements, it prevents overheating and supports long-term motor reliability in demanding industrial environments.

Why It Helps
The FH80 heater element ensures precise tripping of Type A and Type B overload relays by heating proportionally to the motor’s full load current. This enables consistent performance, proper coordination with 40°C rise motors, and dependable protection across the supported FLA range.

Key Highlights

• Designed for 3-phase A200 starter sizes 3 and 4, the FH80 supports accurate thermal overload protection when installed in compatible Type A or Type B relay blocks.

• Rated for motors with a 40°C temperature rise and a 1.15 service factor, helping ensure correct trip timing and reliable response under heavy loads.

• Supports full-load current ranges of Ambient 41.6–56.3A and Non-Compensating 38.3–42.6A, enabling proper heater selection based on motor nameplate values.

• Simple installation using the included mounting screws allows secure attachment directly to the overload relay.

Applications
Used in industrial motor starter assemblies requiring dependable thermal overload protection, including pumps, fans, conveyors, and general-purpose 3-phase equipment. The FH80 ensures reliable operation and maintains protection integrity when properly sized to the motor’s FLA rating.
