Siemens SENTRON 3VA2116-5KP32-0KH0 — 160 A MCCB, 3-Pole, Line Protection
The Siemens SENTRON 3VA2116-5KP32-0KH0 is a molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel design in warm enclosures. Three-pole construction with a line protection design means it is intended for feeder and main breaker duty, not motor protection — the trip curve is fixed for cable and busbar protection. Interrupting capacity reaches 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low, so verify system SCCR if the breaker is applied at that voltage level.
Dimensions and Panel Fit
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA frame size that fits existing switchboard cutouts and DIN-rail adapter plates. At 25.5 W maximum power loss, ventilation in the enclosure should be considered if multiple breakers are ganged; the operating temperature range of -25 °C to 70 °C covers most industrial environments.
Auxiliary and Communication Options
This variant includes a shunt trip (STL) auxiliary release and two auxiliary switches plus one trip alarm switch (HQ configuration), giving remote trip capability and status feedback. A communication function is present.
