Its adjustable trip class (10A, 10E, 20E) lets you match the overload curve to the motor's starting profile — a 10E class clears fast on a high-inertia load without nuisance tripping, while 20E gives more headroom for longer acceleration.
Breaking capacity drops with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. For 400 V panels the 242 kA rating gives substantial SCCR headroom for most industrial service entrances.
Motor protection and thermal performance
The adjustable trip class (10A, 10E, 20E) covers most low-voltage motor applications; 10A is for short acceleration times (conveyors), 20E for high-inertia loads (fans, centrifuges). Insulation voltage rated at 800 V gives margin above the 600 V class.
Panel integration
Fits standard 3-pole MCCB mounting footprints; no special adapter plate needed for most switchboard or enclosure cutouts. Maximum power loss 19.7 W — account for that in enclosure thermal calculations, especially in sealed stainless steel boxes.
