The adjustable thermal-magnetic trip unit covers 600 A minimum to 4800 A maximum, letting you dial the instantaneous pickup to match the inrush of motor loads or the fault tolerance of feeder cables without swapping the breaker body. Interrupting capacity is the headline here: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V.
A mechanical trip indicator gives a visible flag when the breaker has opened on fault, so a tech walking the line can spot a tripped unit without opening the door.
The 110 mm depth means it clears typical gland plates and rear-mounted bus bars without interference. Power loss is rated at 66 W maximum — relevant for thermal calculations inside a sealed enclosure; you'll want to account for that heat load if the panel is NEMA 12 or 4X with limited convection. The 70 °C operating ceiling matches the continuous-current derating table (flat 400 A all the way up), so no need to upsize for a hot electrical room.
