The adjustable overload release is set via a dial from 5.5 A to 8 A, letting you match the breaker to the motor nameplate FLA without swapping hardware. The S00 footprint (45 mm wide) fits standard panel layouts and leaves room for adjacent contactors in a motor starter stack.
This breaker combines a thermal bimetal overload release (CLASS 10) with a magnetic instantaneous short-circuit trip set at 104 A. The thermal element protects against sustained overloads and phase-loss conditions; the magnetic element clears a bolted fault at 104 A without waiting for the thermal curve. At 400 V AC the unit is rated for 3,000 W motor output, and the switching capacity at 400 V is 50 kA (per the SIRIUS family rating for this size). Power dissipation is 9.25 W total in hot operating state, 3.1 W per pole — relevant for enclosure thermal calculations when grouping multiple breakers in a panel.
