Breaking capacity hits 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V — that 330 kA figure at 240 V covers high-fault utility feeds and transformer secondaries.
Trip curve and internal accessories
Adjustable short-time delay from 4 s to 17 s, letting you coordinate downstream with feeders or upstream with a main breaker without nuisance tripping on motor inrush. Trip indicator on the front face gives a local visual flag when the breaker has opened on a fault, which speeds troubleshooting on a multi-breaker panel.
Maximum power loss of 4 W at rated load keeps heat rise manageable inside a sealed enclosure; no forced ventilation required for a single unit.
The basic switch assembly carries its own order code 3VA2163-7MN36-0AA0, which is the internal switching mechanism; the -0AJ0 suffix denotes the complete breaker with the auxiliary switch and trip alarm pre-installed.
