It is a straight disconnect — no overload relay, no short-circuit protection built in — so it serves as a manual load-break isolating point in a distribution or motor feeder circuit where upstream protection is already handled by a separate MCCB or fuse. ## What the 400 A rating means for fit The 400 A continuous rating on the IEC frame 400 tells you the switch can carry that current in free air without exceeding its temperature rise limits. In a closed panel with multiple devices ganged, expect to derate per IEC 60947-1 — typical practice is 80% of nameplate for a sealed enclosure. The switch disconnector is rated for making and breaking load current, not fault interruption; the upstream protective device clears the short. ## What is included on the switch The nut keeper kit secures the busbar or cable lugs to the switch terminals — a detail that saves a trip to the hardware bin during panel assembly. The 3VA1 frame 400 mounts on a mounting plate or DIN rail via the supplied adapter kit. It is a panel-mount device, not a snap-on DIN rail breaker — plan for screw-fixing into the backplate. The 3-pole footprint matches standard SENTRON 3VA1 switch-disconnector cutouts; if you are replacing a failed unit, the mounting hole pattern and busbar centers are identical across the frame-400 family.","metaTitle":"SENTRON 3VA1340-1AA32-0AB0 Switch Disconnector, 400A, 3-Pole","metaDescription":"SENTRON 3VA1340-1AA32-0AB0 switch disconnector, 400A rated, 3-pole, IEC frame 400.
