That means you can coordinate it downstream of a larger feeder breaker or upstream of a motor starter without guessing at the trip bands. Insulation voltage rated 800 V, so it's comfortable on 480 V or 600 V class systems. This breaker clears 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 415 V (common IEC industrial voltage) you still have 121 kA, which covers virtually any panelboard fault current you'll encounter. The drop to 3.7 kA at 690 V means if you're on a 690 V mining or marine system, this breaker is only suitable where the available fault current is very low — verify your SCCR study before specifying. Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is a standard 3-pole MCCB footprint — it fits the same panel cutout and busbar spacing as other 3VA2 three-pole breakers. Depth of 86 mm (3.39 in) means it clears most shallow enclosures; no special rear-access requirement. Indoor panel use only.","metaTitle":"Siemens 3VA2163-5HN32-0AA0 SENTRON MCCB, 63 A, 3-Pole, ETU35","metaDescription":"Siemens 3VA2163-5HN32-0AA0 SENTRON 3-pole MCCB, 63 A continuous, 187 kA at 240 V.
