SENTRON 3VA2116-5HL32-0AH0 — 160 A MCCB, Line Protection Duty
The Siemens SENTRON 3VA2116-5HL32-0AH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current, designed specifically for line protection in distribution panels. It carries a 187 kA breaking capacity at 240 V, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so the interrupting capability drops sharply above 500 V, which matters when you're coordinating with upstream gear on a 690 V bus. Rated insulation voltage is 800 V, and the breaker dissipates a maximum 25.5 W at full load — a figure to account for in enclosed panel thermal calculations, especially when grouping multiple breakers.
Fit and Mounting — Panel Integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that drops into existing Siemens switchboard and distribution panel cutouts without adapter plates. The 3-pole format with line-protection trip curve is the common choice for feeder and main breaker positions in 160 A rated panels.
Auxiliary Switching and Indication
This variant includes 2 auxiliary switches plus 1 trip alarm switch (HQ configuration), giving you remote status of the breaker position and a dedicated alarm contact for fault tripping. The trip indicator is present on the front face — useful for a quick visual check on the panel door without opening it.
