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. 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.
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.
