The TM240 thermal-magnetic trip unit gives overload protection adjustable from 560 A to 800 A (Ir), and short-circuit protection fixed at 5× In (Ii = 4000 A). The ATAM designation indicates the trip unit is adjustable, thermal-magnetic, with a specific time-current curve profile for line protection — typical for main feeders or large motor control center incomers where you need selectivity with downstream breakers. ## Integrated accessories — what's on board The UVR drops the breaker on loss of control voltage — standard for emergency-stop chains or undervoltage protection on motor feeders.","metaTitle":"Siemens 3VA1580-5EF32-0CL0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA1580-5EF32-0CL0 IEC frame 1000 circuit breaker, 3-pole, 800A, Icu=55kA @ 415V.
