The 3VA2216-5HL32-0DA0 is a Siemens SENTRON molded case circuit breaker (MCCB) rated for 160 A continuous current across the full operating temperature range from -25 °C to 70 °C — no derating needed up to 70 °C ambient. That 160 A is the frame rating; the adjustable thermal-magnetic trip unit covers 240 A minimum to 1 920 A maximum, so this one breaker body can serve a wide range of downstream protection settings without swapping hardware. The 3-pole configuration suits three-phase line protection, and the integrated undervoltage release (UVR) lets a safety circuit or upstream contactor drop the breaker on loss of control voltage.
The interrupting rating is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. For a 480 V panel (common in North America) the relevant figure is the 440 V rating — 121 kA — which covers most high-fault installations.
The 105 mm width is standard for a 3-pole MCCB in this class — fits a typical 4-inch (101.6 mm) wide DIN-rail slot with a small margin.
