What this breaker carries
The Siemens 3VA2063-5HL36-0DE0 is a 3-pole IEC frame 100 molded-case circuit breaker with a 55 kA interrupting capacity at 415 V AC — class M breaking capacity, so it clears high-fault currents on industrial distribution without upstream coordination headaches. The ETU320 electronic trip unit provides LI (long-time and instantaneous) protection, adjustable overload Ir from 25 A to 63 A, and short-circuit pickup Ii from 1.5 to 12 x In. That adjustable range lets you dial in the cable and load protection without swapping the breaker body.
Integrated accessories
Factory-fitted with an undervoltage release rated 208–230 V AC, 50/60 Hz, and four HQ auxiliary switches — so it drops the load on loss of control voltage and reports position back to the PLC or status panel. Clamp terminals accept copper conductors without lug kits. Mounts on standard DIN rail or panel; the 3VA2 family shares a common footprint across frame sizes, simplifying panel layout changes.
