SENTRON 3VA2 line protection MCCB — 63 A, 3-pole
Three-pole configuration, rated insulation voltage 800 V. Breaking capacity is the headline number here: 242 kA at 240 VAC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. The drop to 3.7 kA at 690 V is typical for this class; the 690 V rating governs the high-voltage end, not the common 400/480 V range where it still holds 187 kA.
Fit and mounting — panel integration
That gives you a remote status contact for the breaker position and a separate contact that changes state only on a trip event — useful for PLC-based alarm annunciation without extra wiring.
