What this MCCB brings to a panel
The integrated undervoltage release (UVR) drops the breaker on loss of control voltage, which is a common requirement in safety circuits and emergency-stop chains on a paper machine or conveyor line.
This breaker delivers 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. The 415 V figure is the one most European industrial panels care about; 32 kA covers most distribution boards downstream of a transformer.
Temperature derating — when the panel runs hot
At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A.
The 3VA1063-2ED42-0DA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. No auxiliary contact version is fitted as standard; if you need status feedback to a PLC, order the auxiliary trip accessory (order code 3VA9608-0BB25) separately.
