The Siemens SENTRON 3VA2116-5HN36-0AJ0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C — no derating needed across that span, which simplifies panel design in warm enclosures. Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. It is a line-protection device (no ground-fault monitoring, no undervoltage release, no communication module) — a straightforward main or feeder breaker for distribution panels, motor control centers, and switchboards.
Breaking capacity — what the voltage steps tell you
The 187 kA at 240 V is the headline number, but the 121 kA at 415 V is the one that matters for most European and Asian 400 V class panels. At 500 V it still holds 75.6 kA — enough for most industrial 480 V feeds in North America. The drop to 3.7 kA at 690 V means this frame is not intended for high-impedance 690 V systems; if your line side is 690 V with significant fault current, you need a larger frame or a current-limiting upstream device.
Physical fit and auxiliary wiring
No communication function, no undervoltage release, no shunt trip — if you need remote trip or status over a bus, this is not the variant. The supplied basic switch order code is 3VA21165HN360AA0, which is the internal switching mechanism; you order the complete breaker as 3VA2116-5HN36-0AJ0.
