It carries a continuous current rating of 63 A across the full ambient temperature range from 40 °C to 70 °C, so no derating curve to track when the panel runs hot. The 3-pole construction suits three-phase distribution in industrial switchboards, panelboards, and machine supply feeders.
At 240 V it interrupts 242 kA; at 415 V and 440 V it handles 187 kA; at 500 V it clears 121 kA. The sharp drop to 3.7 kA at 690 V means this breaker is sized for 400 V class distribution, not 690 V industrial networks. For a 480 V panel in North America the 121 kA figure at 500 V is the relevant benchmark — well above typical available fault currents in most commercial and light industrial services.
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 105 mm width is three 35 mm DIN increments — it occupies three adjacent 35 mm module positions on a DIN rail, which is standard for a 3-pole MCCB in this frame size.
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The breaker includes a trip indicator but no undervoltage release and no communication function — it is a straightforward thermal-magnetic or electronic trip unit (the evidence does not specify trip technology) for line protection only.
