It carries 63 A continuously at 40 °C (derated to 58 A at 70 °C) and interrupts up to 187 kA at 240 VAC — that is the figure that governs fault-clearing duty in a 240 V panel. At 415 V the interrupting rating is 121 kA, dropping to 75.6 kA at 440 V and 17 kA at 500/690 V, so the SCCR headroom depends on your system voltage. Three-pole construction with no undervoltage release and no auxiliary switch fitted as standard — the basic switch is order code 3VA11635ED320AA0, and the design allows up to four HQ auxiliary switches to be added later.
The 3VA1163-5ED32-0AE0 holds a full 63 A up to 50 °C ambient; above that it derates linearly to 58 A at 70 °C. That means in a tightly packed panel at 55 °C you have 62 A available — still enough for a 63 A bus if the load is below the curve. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into the existing SENTRON 3VA mounting base without rewiring. The 76.2 mm width (3 in) matches the panel cutout for earlier 3VA frames, so a swap from a 3VA1110 variant is a straight mechanical fit.
