Ratings & What They Mean for Fit
The 3VA1063-2ED42-0KH0: Rated continuous current Iu of 63 A at 40 °C, 45 °C, and 50 °C — no derating needed in typical panel ambient. At 55 °C it holds 60.48 A, at 60 °C it holds 59.22 A, and at 70 °C it holds 56.7 A. The TM210 thermal-magnetic release is fixed for line protection; the 15000-cycle latching endurance suits frequent switching in distribution panels or machine feeder circuits. Breaking capacity: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. This means the MCCB safely interrupts fault currents up to those levels without upstream coordination failure — critical for high-fault panels in industrial or commercial mains. The 800 V rated insulation voltage (Ui) covers 480 V and 600 V class systems. Four poles, no N-conductor protection — this is a 3-pole + solid neutral or 4-pole ungrounded configuration, depending on system design. The front IP40 rating means it's protected against tools >1 mm but not washdown; mount inside a sealed enclosure for wet environments.
Deployment Context
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. Fits standard SENTRON 3VA panel cutouts and busbar systems. The integrated shunt trip (STL) auxiliary release (order code 3VA9688-0BL33) allows remote tripping from an E-stop or PLC output. Auxiliary contact block includes 2 auxiliary switches plus 1 trip alarm switch (HQ) for status feedback to a controller or HMI.
