The thermal-magnetic trip means no electronic adjustment; overload protection is fixed at 40 A and short-circuit pickup at 400 A (10 × 40 A). The breaker includes a shunt trip (STL) rated for 12–30 V DC and 24 V AC at 50/60 Hz, plus two auxiliary switches (HQ) and one trip alarm switch (HQ). The auxiliary contacts signal the breaker's open/closed state to a PLC or status lamp; the alarm switch changes state only when the breaker trips on fault, not on manual opening — useful for a remote fault annunciation. ## Integration and deployment Clamp-type line and load terminals accept copper conductors up to the frame's rated cross-section (typically 35 mm² for this frame). The shunt trip and auxiliary switches are factory-installed; no field-assembly of internal accessories is required. The breaker occupies three modular width units (3 × 18 mm) on the DIN rail.","metaTitle":"Siemens 3VA1040-3ED36-0HH0 Circuit Breaker, 40A, 25kA @ 415V","metaDescription":"Siemens 3VA1040-3ED36-0HH0 IEC frame 100, 3-pole, 40A fixed thermal-magnetic, 25kA Icu @ 415V, shunt trip, aux switches.
