SENTRON 3VA2163-5HL32-0BH0 — 63 A MCCB with ETU320 and Undervoltage Release
Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. The 63 A rating holds from 40 °C through 50 °C, then derates linearly to 53.55 A at 70 °C — useful for panel builders working with elevated ambient temperatures inside enclosures.
The 3-pole form factor with screw terminals accepts standard busbar and cable connections. Power loss is 6.5 W maximum, which keeps thermal rise manageable in dense panels. Mechanical endurance is rated at 20,000 operations, and the operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C.
Trip Unit and Auxiliary Configuration
No communication function, phase failure detection, or ground fault monitoring is included on this variant — it is a pure line-protection device.
