It is a 3-pole unit rated 500 A at 40 °C, with a continuous current rating that holds at 500 A up to 50 °C, then derates to 495 A at 55 °C, 490 A at 60 °C, 485 A at 65 °C, and 480 A at 70 °C — so for panels running warm, the effective ampacity is the 55 °C or 60 °C line, not the 40 °C headline. Breaking capacity varies sharply with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. Built-in phase failure detection and an undervoltage release are standard on this variant, so it handles the two most common motor-protection trip conditions without add-on modules.
Dimensions: 248 mm height, 138 mm width, 110 mm depth. Depth of 110 mm leaves clearance behind the panel for wiring and the undervoltage release coil.
Thermal and storage limits
Maximum power loss is 101.5 W — relevant for thermal management inside a sealed enclosure. If the panel also contains drives or transformers, factor this into the cooling calculation.
