The thermal-magnetic trip unit (TM220, ATFM) gives you adjustable overload protection from 14 A to 20 A and a fixed short-circuit pickup at 16 times the rated current (In=20 A). In a real panel, that governs whether the breaker coordinates with upstream gear (transformer secondary, main breaker) and whether it meets the available fault current at its mounting point. The adjustable overload Ir (14–20 A) lets you dial in the exact motor or feeder load without swapping trip units, which saves a panel rewire if the load changes slightly.","metaTitle":"Siemens 3VA1120-5EE32-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1120-5EE32-0AA0-ZD00 IEC frame 160 circuit breaker, 55kA breaking capacity at 415V, 20A thermal-magnetic protection.
