The Siemens SENTRON 3VA2163-5HL36-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, designed for line protection in distribution panels. It carries an insulation voltage rating of 800 V, and its breaking capacity scales with system voltage: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
The breaker occupies 105 mm width, 181 mm height, and 86 mm depth on the panel. Three-pole footprint matches standard MCCB cutouts.
At 415/440 V the rating drops to 121 kA — still high enough for most industrial secondary distribution. At 690 V the rating falls to 3.7 kA, so this breaker is not suited for 690 V main feeders with high available fault current; it belongs on lower-level subfeeds at that voltage.
