Above 50 °C the thermal curve steps down: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. That means a panel running at 55 °C ambient loses 4 A of headroom — a detail the spec table alone doesn't flag, but one that matters for a BOM freeze in a warm enclosure. Breaking capacity is rated per the evidence at 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. An undervoltage release (UVR) is fitted as standard, and the auxiliary contact block is a 2-switch HQ version (order code 3VA9608-0BB25 for the integrated auxiliary trip). No ground-fault monitoring or phase-failure detection is included.
Deployment context
The 76.2 mm width (roughly 3 inches) and 130 mm height fit a typical 3-pole MCCB footprint; the 70 mm depth leaves clearance for rear-connected busbars or cable ducts.
