What the ratings mean for fit
The 3VA1116-6EF32-0AF0 is a 3VA1 IEC frame 160 molded case circuit breaker with breaking capacity class H, rated Icu = 70 kA at 415 V. That 70 kA interrupting rating at 415 V means it clears high-fault currents in industrial distribution without upstream cascading — sized for main or large feeder panels where available fault current is high. The TM240 line protection unit provides thermal-magnetic overload and short-circuit protection. Overload current Ir is adjustable 112...160 A, and short-circuit pickup Ii is adjustable 5...10 x In. It ships with a nut keeper kit, one auxiliary switch HQ, and one trip alarm switch HQ — the aux and alarm switches are already fitted, which saves panel-builder wiring time for status feedback to a PLC or annunciator.
Deployment context
This MCCB mounts in a standard IEC distribution panel or enclosure. The 3VA1 frame 160 is a compact IEC design — three-pole, bolt-on or plug-in base, with tunnel-type terminals for cable up to the rated cross-section. The included auxiliary and alarm switches reduce the need for add-on blocks on the side.
