Interrupting capacity and coordination
The 79 kA at 500 V and 4.25 kA at 690 V cover the voltage bands common in 690 V mining or marine distribution. The 20 000 latching-endurance cycles support frequent switching in process lines.
At 55 °C it holds 60.6 A, at 60 °C 58.3 A, at 65 °C 55.9 A, and at 70 °C 53.6 A — usable in a hot panel if you size the load accordingly. That width matches the standard 3-pole MCCB footprint on most DIN-rail adapter plates. The max power loss of 4 W at rated current keeps internal cabinet temperature rise manageable.
