The thermal-magnetic trip unit (TM240, ATAM) provides adjustable overload protection (Ir = 14…20 A) and fixed short-circuit pickup (Ii = 8…16 × In, so 160…320 A at the 20 A rating). That adjustability lets the panel builder fine-tune the overload band to the connected load without swapping the breaker body. The integrated undervoltage release (UVR, 208–230 V AC 50/60 Hz) drops the breaker open when control voltage falls below its dropout threshold — a standard requirement in safety circuits that need a fail-safe disconnect on loss of control power.","metaTitle":"Siemens 3VA1120-5EF36-0DH0 Circuit Breaker, 55kA @ 415V, 20A","metaDescription":"Siemens 3VA1120-5EF36-0DH0 IEC frame 160 MCCB, 55kA breaking capacity at 415V, 20A thermal-magnetic, undervoltage release.
