Siemens SENTRON 3VA2163-5HL42-0AA0 — 63 A MCCB, Line Protection, ETU320 Trip
It carries an interrupting capacity of 187 kA at 240 V AC, derating to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so at typical 400 V class supply voltages it clears faults up to 121 kA without cascading upstream. Dimensions are 181 mm height, 140 mm width, and 86 mm depth — a standard footprint for a 4-pole frame in this class. The breaker does not include an undervoltage release, ground-fault monitoring, or communication function; it is a straight line-protection device with the ETU320 as the only intelligent element.
Panel Integration & Mounting
The 140 mm width occupies roughly 5.5 inches of rail space for the 4-pole frame. Spring-cage terminals accept copper conductors sized for the 63 A rating; verify lug torque per the installation instructions.
