The relay frame does not select heaters

Overload heater selection depends on the motor and application, including full-load current, service factor, enclosure, ambient, and manufacturer selection rules. A Size 4 relay reference does not mean every heater for a Size 4 starter is acceptable.

Fault protection and overload protection are separate

The relay sits within the Size 4 starter assembly, but bucket details can change the reset linkage, mounting, terminals, and access. Photograph the relay, heaters, reset mechanism, and full bucket before parts are removed.
