It carries a TM220 thermal-magnetic trip unit with a 40 A nominal rating (In), adjustable overload protection (Ir) from 28 A to 40 A, and a fixed short-circuit protection (Ii) at 10× In. The ATFM designation indicates the trip curve and accessories configuration. A nut keeper kit is included for DC Power OEM installations in China. The TM220 thermal element provides inverse-time overload protection for cables and moderate motor starts, while the magnetic element (Ii = 10× In, or 400 A) handles short-circuits. The adjustable Ir (28–40 A) lets you fine-tune the overload threshold to match the downstream load without swapping the breaker.","metaTitle":"Siemens 3VA1140-5EE32-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1140-5EE32-0AA0-ZD00 circuit breaker, IEC frame 160, 55kA breaking capacity @ 415V, 40A TM220 overload protection.
