What this MCCB does on the line
Its 3-pole design and line-protection profile make it a straight fit for feeder or main breaker duty in a distribution panel, sized for a 160 A bus. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V, so it handles high-fault scenarios common in industrial switchgear without cascading upstream.
At 415 V and 440 V it still delivers 121 kA, and at 500 V it holds 75.6 kA. The trip indicator gives a visible flag when the breaker has opened on fault, speeding up fault isolation on a crowded panel.
Integration and auxiliaries
That gives remote status feedback — auxiliary for open/closed, trip alarm for fault-trip only — without needing a separate accessory order. If you need those, this isn't the build. The basic switch base is order code 3VA2216-5HL32-0AA0, so the -0AJ0 suffix adds the auxiliary switch package.
