Motor protection circuit breaker with integrated auxiliary contacts
It combines a Class 10 overload trip unit adjustable from 5.5 to 8 A with a fixed instantaneous magnetic trip set at 104 A. The screw terminal connections are rated for standard switching capacity — suitable for most fixed-speed motor applications in industrial control panels. The multi-unit packaging (24 units per pack) suggests this is a volume-stocked line item for panel builders or OEMs with consistent BOM consumption.
The 5.5 to 8 A overload adjustment range covers motor FLA from about 5.5 A (roughly 2.2 kW at 400 V) up to 8 A (about 4 kW at 400 V). The 104 A instantaneous trip is a fixed magnetic threshold — it clears short-circuit faults above that level without waiting for the thermal bimetal. The 1 NO + 1 NC auxiliary switches are wired into the control circuit for status feedback (run/fault indication) or to interlock with a contactor coil. The screw terminals accept standard ring or fork lugs; torque per the terminal marking on the device face.
