The Siemens SENTRON 3VA2216-7KQ32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current, with an adjustable thermal-magnetic trip unit covering 32 A to 160 A. Its interrupting ratings are 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V — the 690 V figure drops sharply, so confirm the available fault current at that voltage before specifying.
The 160 A continuous rating is the breaker's thermal capacity at 40 °C ambient; it holds flat at 160 A from 40 °C through 70 °C (–), so no derating is needed across typical panel ambient temperatures. The adjustable trip range from 32 A to 160 A lets you match the breaker to the actual load without swapping the frame — useful for BOM consolidation when the same panel build serves multiple current tiers. That makes it suitable for panels where remote monitoring or ground-fault detection is required without a separate relay.
Verify gland-plate clearance for the 86 mm depth, especially in shallow enclosures.
