The Siemens 3VA1010-2ED42-0HC0 is a 4-pole IEC frame 100 circuit breaker rated at 100 A continuous current with a breaking capacity of 16 kA at 415 V (switching capacity class B).
The TM210 thermal-magnetic trip unit is fixed at Ir = 100 A (overload) and Ii = 10 × In = 1000 A (short-circuit). The instantaneous pickup at 1000 A is fast enough to clear a bolted fault before let-through energy damages downstream components, but it is not a selective (short-time-delay) trip; if you need zone selectivity, you step to the electronic trip versions in the 3VA1 family. If your installation requires neutral protection (e.g., 4-wire distribution with high harmonic content), this is not the right order code. The shunt release (STL) operates on 12-30 V DC or 24 V AC 50/60 Hz — a wide DC range that covers common 24 V control voltages, including battery-backed supplies. The 2 HQ auxiliary switches provide status feedback for remote monitoring or PLC interlocking.
Integration notes
Lug terminals accept standard power conductors; shunt release wiring lands on accessory terminals.
