That 630 A is the thermal rating at 40 °C ambient; at 45 °C it carries 600 A, and it derates steadily to 450 A at 70 °C — so the real-world capacity depends on your enclosure's internal temperature, not just the nameplate number. For a panel running at 50 °C, plan on 570 A continuous. The interrupting capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The ETU850 electronic trip unit handles overcurrent protection. The breaker includes a communication function for remote monitoring.
Lifecycle and sourcing — current production, quoted to order
The maximum power loss is 162 W, which matters for thermal management inside the enclosure. If you are packing multiple breakers in a confined panel, that heat load adds up — factor it into your ventilation or derating calculation.
Integration — footprint and panel fit
The depth of 110 mm includes the front cover; allow clearance for the communication module if fitted. That is typical for a panel-mounted breaker — the enclosure provides the overall IP rating. The auxiliary contact version is 2 auxiliary switches HP (high-performance), giving you two sets of changeover contacts for status feedback.
