The 3-pole body carries an 800 V rated insulation voltage, so it's comfortable on 400/480 V panels.
This MCCB delivers 187 kA at 240 V AC, which drops to 121 kA at both 415 V and 440 V, then 79 kA at 500 V, and 4.25 kA at 690 V. At 415 V, the 121 kA rating still covers heavy industrial service-entrance duty. The steep drop to 4.25 kA at 690 V means this isn't the breaker for a 690 V high-fault panel — you'd need a higher-rated frame for that leg.
At 55 °C it steps to 60.6 A, at 60 °C to 58.3 A, at 65 °C to 55.9 A, and at 70 °C to 53.6 A. If your panel sits near a furnace line or in a hot attic, factor that derate into your load schedule.
Integrated auxiliaries and releases
Comes with an undervoltage release (UVR) already fitted — part number 3VA9608-0BB25 — and 2 auxiliary switches (HQ type). No ground-fault monitoring or communication module on this variant, so if you need GF or remote status, you're adding those externally.
