The Siemens SENTRON 3VA2163-6HL32-0AB0 is a 3-pole molded case circuit breaker rated at 63 A continuously from 40 °C all the way up to 70 °C — no derating curve to chase across the panel ambient range. That flat thermal rating simplifies BOM planning for enclosures that run warm. 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 — high enough for most transformer-fed industrial service entrances and large motor control centers.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into existing SENTRON 3VA2 panel cutouts and busbar systems. The breaker ships with two HP auxiliary switches integrated, so you get status feedback without adding external contact blocks. Maximum power loss is 4 W, which keeps heat rise low in a dense panel.
