63 A MCCB with full-rated interrupting capacity across voltage bands
The Siemens SENTRON 3VA2063-5HL36-0AJ0 is a 3-pole molded case circuit breaker rated for 63 A continuous current, with no derating required from 40 °C through 70 °C ambient. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — meaning it clears high-fault currents across common industrial voltage levels without cascading upstream. The 800 V rated insulation voltage supports 690 V line-to-line systems with margin.
Panel fit and auxiliaries
Footprint is 105 mm wide, 181 mm tall, 86 mm deep — standard SENTRON 3VA2 frame size. Ships with 2 auxiliary switches plus 1 trip alarm switch (HP design) pre-installed, so no separate add-on order for status feedback. Line protection design means thermal-magnetic or electronic trip tuned for cable/feeder protection out of the box.
Power loss and environmental limits
Maximum power loss is 5.4 W, low enough for dense panel layouts without forced cooling. Operating range -25 °C to 70 °C; storage range -40 °C to 80 °C. No ground-fault monitoring version, no undervoltage release, no communication function on this order code.
