What this 160 A MCCB delivers
The Siemens SENTRON 3VA2216-5HL42-0AA0 is a 4-pole molded case circuit breaker rated for 160 A continuous current, carrying that rating flat from 40 °C through 70 °C ambient — no derating curve to chase in a warm enclosure. The ETU320 electronic trip unit gives you an adjustable overload pickup from 240 A up to 1,920 A, so one breaker body covers a wide range of downstream protection settings. Insulation voltage is rated 800 V, and the interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — a steep SCCR curve that matters when you're coordinating with upstream gear. Maximum power loss is 19.7 W.
Sourcing and lifecycle posture
Lifecycle stage is listed as current — no phase-out notice, no last-time-buy window. This is a standard catalog item from the SENTRON family. No undervoltage release, no communication function, no ground-fault monitoring version on this variant; it's a straight thermal-magnetic replacement with electronic trip adjustment. For a BOM freeze or a panel that needs a second-source gate, the closest functional peer is the 5SQ2670-2YA06 series — same frame size and trip range, but verify the terminal arrangement and accessory compatibility before swapping. We source this breaker to order against an RFQ; availability and current pricing are confirmed at quote time.
