What's in the box
The Siemens 3VA2063-5HL32-0HA0 is a current-production IEC molded-case circuit breaker on the 3VA2 platform, frame 100, with a 55 kA interrupting capacity at 415 V — that's the M breaking capacity class, meaning it handles moderate fault levels typical of industrial distribution panels without cascading upstream. Three poles, line protection via the ETU320 electronic trip unit with LI (long-time and instantaneous) curves. Rated continuous current In = 63 A, with overload protection adjustable Ir from 25 A to 63 A, and short-circuit pickup Ii adjustable 1.5 to 12 times In. Ships with the nut keeper kit and a shunt trip (STL) coil rated 12–30 V DC or 24 V AC 50/60 Hz.
The ETU320 is an electronic trip unit, so it holds its calibration over temperature better than a thermal-magnetic; the LI curve gives you adjustable long-time pickup (Ir) for cable protection and adjustable instantaneous (Ii) for motor-start inrush or selective coordination. The shunt trip (STL) on 12–30 V DC or 24 V AC lets you remote-trip from an E-stop or PLC output without a separate interposing relay. Mounts in a standard IEC panel on a DIN rail or direct-screw pattern — verify the frame-100 footprint against your existing bus bars.
