That 630 A figure is the thermal rating at the panel's ambient — derate it per the curve: at 50 °C it's 593 A, at 60 °C it's 557 A, and at 70 °C it's 520 A. The overcurrent release is an ETU350 electronic trip unit, which gives you adjustable long-time, short-time, and instantaneous pickup settings — not a fixed thermal-magnetic curve. Breaking capacity hits 330 kA at 240 V and stays at 242 kA at 415 V and 440 V, then drops to 187 kA at 500 V and 52.5 kA at 690 V.
Deployment and integration
This MCCB is a panel-mount device — it bolts into a switchboard or distribution panel, not a DIN rail. The 3-pole footprint measures 138 mm wide by 248 mm tall by 110 mm deep, so check your panel's cutout and bus-bar spacing before committing. The integrated auxiliary trip module is order code 3VA9688-0BL30; the supplied basic switch is 3VA2463-7HN32-0AA0.
