What it is and what it does
The Siemens SENTRON 3VA2163-6HL36-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 63 A, designed for line protection in distribution panels. It carries a breaking capacity of 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — these numbers define the maximum fault current it can safely interrupt at each voltage level, which is the primary selection criterion for panel coordination studies.
What the ratings mean for fit
The 63 A rating holds across the full operating temperature range from -25 °C to 70 °C — no derating needed as the panel warms up, which simplifies panel schedules. The 800 V rated insulation voltage gives headroom for 480 V and 600 V class systems. The 3-pole design suits three-phase feeders; the unit ships with three built-in auxiliary switches (HQ type) for status feedback to a PLC or indication lamp, so you don't need a separate accessory block for basic signaling.
Panel integration notes
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — fits standard MCCB mounting footprints in 600 mm wide enclosures. No undervoltage release, no ground-fault monitoring, and no communication function on this variant; it is a straight thermal-magnetic line-protection breaker with auxiliary contacts only.
