The Siemens SENTRON 3VA2116-5JQ32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 160 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal calculations. The interrupting capacity at 240 V is 187 kA, dropping to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V. The minimum adjustable trip is 240 A; the maximum is 1 600 A, giving a wide band for coordination studies. The communication function (Ethernet or fieldbus via an optional module) allows remote trip indication and status monitoring, which is useful for a line-down diagnostic or SCADA integration.
Maximum power loss is 28 W, which should be factored into enclosure ventilation if the breaker is in a sealed cabinet with other heat sources.
