The ETU330 release provides adjustable time-current curves (tr min 0.5 s to tr max 17 s), giving the panel builder selectivity coordination flexibility downstream.
The 3VA2116-7HM42-0AA0 delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.8 kA at 690 V. The steep drop at 690 V is characteristic of a breaker optimized for 240–500 V distribution — at 690 V it still interrupts, but the 3.8 kA figure means it is not the first choice for 690 V motor circuits unless the fault current is confirmed below that level. For most 400–480 V industrial panels, the 242 kA rating provides generous headroom above typical available fault currents, simplifying coordination studies.
No derating is required up to 70 °C, which simplifies panel layout in warm environments or enclosures with multiple heat sources.
The 140 mm width for a 4-pole frame is standard for SENTRON 3VA2 breakers — verify the existing panel cutout or mounting plate matches this footprint before ordering. Front IP40 protection means it is suited for indoor panel mounting where no water spray is present; for washdown environments, additional enclosure protection is needed. The adjustable N-conductor protection (OFF, 50%, 100%) and ground-fault monitoring via summation current formation on L+N are configured via the ETU330 interface — set these before installation.
Key approvals and compliance documentation
As a Siemens SENTRON product, the 3VA2116-7HM42-0AA0 carries the manufacturer's standard compliance documentation package including CE marking for the European market, and is designed to meet IEC 60947-2 for molded case circuit breakers. For specific UL/CSA listings or RoHS/REACH declarations, the manufacturer's documentation portal provides the current declarations by order code.
