Its fixed 4800 A rating means there's no adjustable trip block to set — what's on the nameplate is what you get, which simplifies BOM matching and reduces commissioning errors on site. Interrupting capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V. At 690 V the 9 kA figure is modest; if your system sits at that voltage with higher fault potential, check selectivity coordination.
Panel fit and thermal management
The 138 mm width per pole is typical for this current class; verify gland-plate cutouts if retrofitting into an existing enclosure. Maximum power loss is 63.5 W. In a sealed or tightly packed panel that's enough heat to matter — leave breathing space around the breaker and check the enclosure's dissipation capacity if you're stacking multiple units. The storage bottom end is fine for unheated warehouses in cold climates, but if the breaker sees continuous condensation or freezing conditions during operation, the -25 °C floor is the limit.
Auxiliary switching and variants
This order code includes 3 auxiliary switches (HQ type) built in — no separate add-on module to order and fit. That's three sets of contacts for status feedback, remote indication, or interlocking. The basic switch variant without auxiliaries is order code 3VA2440-5HN32-0AA0. If you need any of those, this isn't the order code — you'd step up to a -5H... suffix with the appropriate release or module.
