Siemens SENTRON 3VA2116-5HL32-0HC0 — 160 A MCCB with High Interrupting Capacity
It carries a continuous current rating of 160 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel layout when the breaker sits near other heat sources. Breaking capacity is the headline number here: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint. Power loss is 25.5 W maximum at rated load — relevant for thermal calculations inside a sealed panel. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C.
