Line protection, not motor protection
This breaker is designated for line protection — feeder and distribution duty, not direct motor overload protection. Pair it with a separate overload relay for motor branch circuits. Rated insulation voltage is 800 V, so it's comfortable in 480 V and 600 V class switchgear. No ground-fault monitoring, no communication module, no undervoltage release on this variant — it's a straight thermal-magnetic MCCB with auxiliary contacts only.
Active lifecycle — no LTB pressure
The basic switch assembly is order code 3VA20106HN320AA0, which simplifies spare-parts planning if the mechanism ever needs replacement.
