The Siemens 3VA1010-3ED42-0AE0 is a 4-pole IEC molded-case circuit breaker in the 3VA1 frame, rated 100 A continuous with a 25 kA interrupting capacity at 415 V AC — switching capacity class N. The TM210 thermal-magnetic trip unit provides fixed overload protection at Ir = 100 A (non-adjustable) and fixed short-circuit pickup at Ii = 10 × In (1000 A).
Deployment context
The lug terminals accept copper or aluminum conductors up to the frame's rated cross-section — no special adapter needed for panel wiring. The four auxiliary switches (HQ) provide remote status indication for the main contacts and trip mechanism, useful for PLC or SCADA monitoring of the feeder circuit.
