What this 3VA1 breaker carries
The Siemens 3VA1010-4ED36-0HA0 is a 3-pole IEC frame 100 circuit breaker with a 36 kA breaking capacity at 415 V — class S in the 3VA1 line. Overload protection is fixed at 100 A (Ir = In), and short-circuit pickup is fixed at 10× In. No adjustment dials on the TM210 thermal-magnetic trip. The integrated shunt trip (STL) operates on 12–30 V DC or 24 V AC, letting a remote emergency-stop or PLC output drop the breaker without pulling the handle. Clamp terminals on line and load sides speed panel wiring — no lug crimping needed for the 100 A circuit.
Where it lands in a panel
Snap-on DIN rail mounting for standard 35 mm rail. The 3-pole footprint matches the 3VA1 family — same width as a 100 A frame, so it fits existing busbar and enclosure layouts without re-drilling. The clamp terminals accept copper conductors typical for 100 A branch circuits. No special tools beyond a screwdriver for the terminal clamps and a DIN-rail stop.
