63 A MCCB with full-rated interrupting capacity across the voltage range
The Siemens SENTRON 3VA2163-5HL36-0AJ0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, with a line-protection trip curve. It carries 187 kA interrupting capacity at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — meaning it clears high fault currents at common distribution voltages without needing an upstream current-limiting fuse. The 63 A rating holds across the full ambient range from 40 °C to 70 °C with no derating, so it can be packed into a warm panel without recalculating the load schedule. Designed for line protection (not motor or generator protection), it mounts on a DIN rail or panel base. The 105 mm width and 181 mm height fit standard SENTRON 3VA2 panel cutouts, and the 86 mm depth leaves room for rear-access cabling.
Auxiliary switch complement and trip indication
This MCCB ships with 2 auxiliary switches plus 1 trip alarm switch (HP type) factory-installed — enough to signal open/closed status and a trip event back to a PLC or alarm panel without adding a separate accessory. The trip indicator is present on the front face, so a walk-by inspection confirms the breaker tripped rather than being switched off.
Current production — no obsolescence concern
The lifecycle stage is marked as current, meaning Siemens continues to manufacture this order code. No last-time-buy notice or successor part is documented.
Sourcing and compliance
The 3VA2163-5HL36-0AJ0 is sourced to order through independent distribution. Availability and current pricing are confirmed at quote time against an RFQ. The breaker carries the SENTRON brand designation and is rated for 800 V insulation voltage. Compliance documentation (RoHS, REACH, UL, IEC) is provided with the shipment per standard Siemens practice.
