It carries an ETU320 electronic trip unit, adjustable from 38 A minimum to 300 A maximum, giving you a wide coordination window for feeder or branch circuits. The interrupting capacity reaches 242 kA at 240 VAC and still holds 187 kA at 415 VAC, so it handles high-fault scenarios without cascading upstream.
At 240 VAC the 3VA2025-6HL36-0AA0 interrupts 242 kA — that is a full-range fault rating for most North American distribution panels. At 415 VAC it still breaks 187 kA, and at 500 VAC it delivers 121 kA. Only at 690 VAC does it drop to 3 kA, so keep that in mind if you are running a 690 V line.
Maximum power loss is 0.84 W, so heat buildup in a crowded panel is negligible.
