What this MCCB delivers in the panel
The Siemens SENTRON 3VA2163-8JP46-0AA0 is a 4-pole molded case circuit breaker rated for 63 A continuous current with no derating across its full operating range up to 70 °C — the same 63 A holds from 40 °C through 70 °C, so you don't lose headroom in a warm enclosure. Its ETU550 electronic trip unit provides adjustable overload and short-circuit protection, with a minimum setting of 95 A and a maximum of 756 A, covering a wide range of feeder and branch circuit needs. Breaking capacity is 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — high enough for most industrial distribution panels with high fault-current potential, and it carries an 800 V rated insulation voltage.
Integration and mounting
The 3VA2163-8JP46-0AA0 measures 140 mm wide, 181 mm high, and 86 mm deep — fits standard panel-mount cutouts for 4-pole MCCBs in the 63 A frame class. Front IP40 protection keeps dust out of the trip-unit interface. A communication function is built in, supporting integration with higher-level monitoring or control systems — no separate comm module required for basic connectivity.
