The interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415/440 V, and 121 kA at 500 V — numbers that tell you this breaker handles high-fault utility feeds or transformer secondaries without cascading upstream. The basic switch supplied is 3VA2325-6HL32-0AA0, so the 0BL0 suffix adds the UVR and the full auxiliary set — a configured variant, not a bare frame.
Panel footprint and thermal budget
The 138 mm width is three-pole wide — verify your busbar centres and phase-to-phase clearance before laying out the gland plate. Maximum power loss is 40 W, which matters for internal temperature rise in a sealed enclosure; if you are packing multiple breakers in a row, sum the losses against your ventilation or cooling capacity.
