Its ETU860M electronic trip unit gives you adjustable trip classes (10A, 10/10E, 20/20E, 30/30E) so you can match the thermal curve to the motor start profile — a 10E class for quick-start pumps, a 30 class for high-inertia conveyors that need a longer ramp.
Phase failure detection and ground-fault monitoring (summation current formation on the L-conductor) are built into the ETU860M, so you don't need a separate ground-fault relay for most motor branch circuits. Communication function is present, which means the trip unit can report status and events over the SENTRON bus system for integration into a plant monitoring scheme.
The 0.5 W maximum power loss is negligible for enclosure thermal calculations — no forced ventilation required for this single unit. Wire the line and load lugs per the terminal markings; the ETU860M draws its power from the internal current transformers, so no auxiliary supply is needed for the trip unit to function.
