The interrupting capacity varies by system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — so the voltage of your fault-current study determines which figure governs your SCCR. The trip unit is set with a minimum of 945 A and a maximum of 5,670 A, giving a wide adjustment band for coordination with downstream devices. Thermal derating is published across the operating range: 630 A at 40 °C, stepping down to 450 A at 70 °C. Dimensions are 110 mm deep, 138 mm wide, 248 mm tall — a standard SENTRON 3VA2 fixed-mount footprint. The basic switch variant is 3VA2463-5KP32-0AA0; this order code adds the undervoltage release and communication stack.
Mounts in a standard distribution panel on a mounting plate — not DIN-rail, but a bolted fixed-mount pattern. The 138 mm width and 248 mm height fit a standard MCCB cutout; verify gland-plate clearance for the 110 mm depth, especially if the panel door has a shallow backpan. The 164.5 W dissipation at rated load means the breaker needs breathing space — avoid stacking it directly above a transformer or drive without a thermal barrier.
