160 A MCCB with 440 kA interrupting capacity — the so-what for your panel
The SENTRON 3VA2216-8KQ42-0AA0 is a 4-pole molded case circuit breaker rated for 160 A continuous current and designed for line protection. Its interrupting capacity hits 440 kA at 240 V and 330 kA at 415 V — that SCCR headroom means it can sit upstream of a high-fault service entrance or a transformer secondary without cascading failure. The 160 A rating holds flat across the full ambient range from 40 °C to 70 °C (–), so no derating headache in a warm enclosure.
Selectivity and coordination — where the 3VA2216 earns its place
With a rated insulation voltage of 800 V and a maximum breaking capacity of 1 920 A, this MCCB is sized for main or feeder duty. The 4-pole construction handles three-phase plus neutral.
Panel integration — dimensions and mounting
The 3VA2216-8KQ42-0AA0 measures 181 mm high by 140 mm wide by 86 mm deep. That 140 mm width is a standard 4-pole MCCB footprint for a 160 A frame.
Communication and monitoring — built-in, not an add-on
This MCCB includes a communication function and an other measurement function. The maximum power loss is 19.7 W. No undervoltage release is fitted, and the trip indicator is not present.
