Eaton FH70 – Frequently Asked Questions

1) How do I pick the right Eaton FH heater for my Size 2 starter?
You size an Eaton A200/B100 heater off the full load amps stamped on the motor nameplate, not off the horsepower or the breaker. The heater element is matched to that FLA figure, and the two models offered here are FH55 and FH70. Pull the nameplate FLA first, then match it to the heater's rated range before you order.
2) How many overload heaters do I need for a three phase motor?
Three. A three-phase motor circuit takes three heaters, one per phase. A single-phase circuit takes two. Heaters are sold individually, so order the quantity your circuit requires rather than assuming a set comes in the box.
3) What is the difference between the Eaton FH55 and FH70 heaters?
Same A200/B100 family, same Size 2 starter application, same Type A and B relay compatibility. The difference is the current rating of the element, which sets the trip point. You choose between them purely on the motor nameplate FLA, so they are not interchangeable on the same motor.
4) Do these Eaton heaters work with Type A and Type B overload relays?
Both. The A200/B100 heater is compatible with Type A and Type B overload relays, which is what the A200/B100 designation refers to. That covers the common Eaton NEMA relay blocks found in motor control centers and starter assemblies.
5) What service factor and temperature rise are these Eaton heater coils rated to protect?
The heater coils are rated to protect a motor with a 40 degree C rise and a 1.15 service factor. If your motor nameplate shows a 1.0 service factor, the standard practice is to select the element more conservatively, because the trip curve on these coils assumes the 1.15 margin.
6) What kind of trip does an Eaton A200/B100 heater give on an overload?
Thermal and fast trip. The element heats in proportion to motor current and trips the overload relay, with fast-trip response for harder faults. It is overload protection only, not short circuit protection, so the branch circuit still needs its breaker or fuses.
