Eaton FH56 – Frequently Asked Questions
1) How many Eaton FH56 heater coils do I need for a three-phase motor?
Three. The FH56 heater coil is sold individually, and a three-phase starter takes three heaters, one per phase. A single-phase application takes two. Order quantity accordingly, because one FH56 on its own will not protect a polyphase motor.
2) What motor full load amps does the Eaton FH56 heater cover?
Pick the heater off the FLA stamped on the motor nameplate, not off horsepower. The FH56 is published with an ambient range of 38.0-415A and non-compensated ranges of 35.3-38.5A and 42.0-45.0A. If your nameplate FLA falls outside the non-compensated bands you need the adjacent heater number instead.
3) Which Eaton starter size does the FH56 heater fit?
The FH56 is used with NEMA Size 2 starters, with Type A and Type B overload relays (hence the A200/B100 designation). It is a NEMA-design heater, so it does not belong in an IEC-style overload relay.
4) Will the FH56 heater protect a motor with a 1.15 service factor?
Yes. Eaton FH56 heater coils are rated to protect a motor with a 40 degree C rise and a 1.15 service factor. For a motor with a different rise or service factor, the selection shifts and you should size from the manufacturer's heater table rather than straight off the FLA band.
5) Does the Eaton FH56 give fast-trip protection or just thermal?
Both. The FH56 is listed as thermal and fast trip, so it covers sustained overload as well as quicker response on a harder fault condition through the Type A or B relay it is installed in.
6) What is the Eaton FH56 heater part number and how big is it?
The manufacturer part number is FH56, an A200/B100 heater coil. It measures 2.1 in long, 1.3 in wide and 0.8 in high, and weighs 0.03 lb, so it is a small clip-in coil rather than an assembly.
