Siemens SENTRON 3VA2163-6HN32-0AJ0 — 63 A MCCB, Line Protection, 3-Pole
The Siemens SENTRON 3VA2163-6HN32-0AJ0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed in a warm panel. Breaking capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — this is a high-interrupting-capacity (HIC) frame suited for high-fault utility or transformer-fed service entrances. Designed for line protection (not motor or generator protection), it ships with 2 auxiliary switches plus 1 trip alarm switch (HP type) factory-installed, and is based on the 3VA2163-6HN32-0AA0 basic switch.
Physical Fit & Panel Integration
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — standard SENTRON 3VA2 3-pole frame footprint, mounts on DIN rail or panel-mount via the accessory kit. Power loss is rated at 4 W maximum — negligible for panel thermal budgeting, but worth noting for tightly sealed enclosures.
Environmental & Compliance
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. No undervoltage release, no ground-fault monitoring, and no communication function on this variant — it is a straightforward thermal-magnetic line-protection breaker.
