It carries a maximum breaking capacity of 187 kA at 240 V AC, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — covering most industrial distribution voltages without needing a frame size bump.
The adjustable thermal-magnetic trip range (95 A minimum to 756 A maximum) means this frame can be tuned for loads well below or above the 63 A continuous rating, though the 63 A continuous is the hard limit for uninterrupted service. At 415 V the 121 kA rating still covers most industrial secondary distribution. Power loss is 5.4 W maximum, low enough that ventilation spacing is standard.
The 3VA2063-5KP32-0JL0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. It includes trip and voltage indicators for quick visual status checks on the panel door.
