What this MCCB is and what it does
The Siemens 3VA2163-5MN32-0JL0 is a SENTRON molded case circuit breaker (MCCB) specifically designed for motor protection, with a continuous current rating of 63 A that holds across the full operating temperature range from -25 °C to 70 °C — no derating needed as the panel warms up. Its interrupting capacity tells you where it can sit in the fault hierarchy: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V is high enough for most service-entrance or large-feeder applications; the drop to 3.7 kA at 690 V means it is not intended for 690 V motor circuits without verifying the available fault current. It carries built-in phase failure detection and a trip indicator, plus a voltage-trigger function — useful for signaling a trip condition back to a PLC or annunciator without adding external relays.
Auxiliary configuration and panel integration
This variant ships with the 3VA21635MN320AA0 basic switch and a full auxiliary complement: two auxiliary switches, one trip alarm switch, and one electrical alarm switch, plus a shunt trip (STL) release. That means you get both status feedback and remote tripping capability in one package — no separate add-on modules to order and wire. Footprint is 105 mm wide by 86 mm deep by 181 mm tall, which fits standard MCCB panel cutouts for this class. No undervoltage release, no ground-fault monitoring, and no communication function on this order code — if you need those, look at the 3VA2 family variants with the UVR or COM options.
Lifecycle and sourcing reality
The 63 A rating across the full temperature range and integrated shunt trip suit motor protection duty with a 3-pole footprint.
