The TMF 200-2000 A trip unit is non-interchangeable — the thermal and magnetic settings are fixed at the factory, so the breaker is sized for a specific continuous current and short-circuit protection curve. For panel builders, this means the trip unit selection is locked at ordering; no field-adjustable dials or interchangeable electronic trip modules on this variant.
