Siemens SENTRON 3VA2163-5HL36-0DA0 — 63 A MCCB with ETU320 and Undervoltage Release
The Siemens SENTRON 3VA2163-5HL36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current (Iu) at 40 °C, with an ETU320 electronic trip unit and an integrated undervoltage release (UVR). Rated insulation voltage is 800 V, and the breaker delivers interrupting ratings of 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 — covering most industrial distribution fault levels. The ETU320 is a basic electronic trip unit for line protection (overload and short-circuit), with no communication function, no phase-failure detection, and no ground-fault monitoring — a straightforward thermal-magnetic replacement in electronic form.
Dimensions are 105 mm wide × 181 mm high × 86 mm deep — a standard 3-pole MCCB footprint for Siemens 3VA2 frames, mounting on a DIN rail or panel baseplate. The breaker accepts a separate auxiliary contact (not included; order 3VA9608-0BB25 separately) and the undervoltage release is factory-integrated, so no field wiring of the UVR coil is required.
Rated 63 A continuous from 40 °C through 50 °C; derates linearly to 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C — account for enclosure ambient when sizing. Maximum power loss is 6.5 W.
