The thermal-magnetic trip unit is a TM240 with an adjustable overload protection range of 14 A to 20 A (Ir) and a short-circuit protection pickup of 8 to 16 times In (Ii). For a 20 A fixed rating, that Ii range is 160 A to 320 A, which covers motor inrush and feeder coordination in standard industrial panels. Mounts on a DIN rail in the distribution section of an industrial control panel. The 3-pole form factor handles three-phase loads — typical for branch protection on motor starters, conveyor drives, or lighting distribution. The adjustable thermal overload (Ir) lets you dial in the exact load current without swapping trip units, which simplifies spares stocking for a panel with mixed 16 A and 20 A circuits.","metaTitle":"Siemens 3VA1120-4EF32-0AA0-ZD00 Circuit Breaker, 36kA @ 415V","metaDescription":"Siemens 3VA1120-4EF32-0AA0-ZD00 IEC frame 160 circuit breaker, 36kA breaking capacity at 415V, 20A adjustable thermal-magnetic protection.

That figure determines the maximum available fault current your panel can handle at that voltage level — critical for UL 508A SCCR compliance."},{"question":"What is the adjustable trip range on this breaker?","answer":"Overload protection (Ir) adjusts from 14 A to 20 A.
