SENTRON 3VA2 — 160 A line-protection MCCB with full-breaking-capacity coverage
The Siemens SENTRON 3VA2116-6HN32-0BH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C. It is designed for line protection (cable and busbar feeder protection) in commercial and industrial distribution panels. Breaking capacity spans from 242 kA at 240 V down to 3.7 kA at 690 V, covering high-fault utility service entrances (242 kA at 240 V) through 690 V industrial loads where the available fault current is lower. At 415 V and 440 V it delivers 187 kA; at 500 V, 121 kA.
Built-in auxiliary and undervoltage release — no separate purchase needed
A trip indicator is present on the front face, giving immediate visual confirmation that the breaker has opened on fault rather than by manual switching.
Footprint and panel integration
Verify the busbar pitch and cable lug centers against the existing panel layout before committing the BOM line.
