The 3VA2010-6HN32-0CA0: Breaking capacity is the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V.
Maximum power loss is 16 W at rated current — a modest heat load, but in a dense panel with multiple breakers, sum them for your enclosure thermal calculation.
Latching endurance is 20,000 operations. No trip indicator, no phase-failure detection, no other measurement function. This is a base-line-protection SKU — the ETU350 gives you adjustable protection curves but no integrated metering or diagnostics.
