The Siemens 3VA1116-6ED36-0KC0 is a 3VA1 IEC frame 160 molded case circuit breaker with a 160 A fixed rating and a 70 kA breaking capacity at 415 V (class H). The breaker includes an integrated shunt trip (STL) rated for 220–250 V DC or 208–277 V AC, plus two HQ auxiliary switches. Connection is via clamp terminals.
The 70 kA Icu at 415 V puts this breaker in the high-breaking-capacity class (H) for the 3VA1 frame. That SCCR matters when coordinating downstream with a transformer or a large motor branch circuit where fault current can exceed 50 kA — it avoids cascading failure upstream. The TM210 trip unit means the thermal element is sized for a 160 A continuous load; there is no adjustment range on Ir or Ii, so the breaker is a fixed-drop-in replacement for a 160 A branch.
Deployment context
The clamp connection accepts copper or aluminum conductors without lug kits, saving install time. The two HQ auxiliary switches provide independent status feedback for the open/closed position — one can feed a PLC input for remote indication, the other can lock out a contactor coil.
