The TM240 ATAM trip unit provides adjustable overload protection (Ir = 280 A to 400 A) and fixed short-circuit protection (Ii = 5 to 10 x In). The thermal-magnetic design means no auxiliary power needed for the trip function — it responds to overload current directly. This variant includes a nut keeper kit and is configured for a DC Power OEM in China, so the termination hardware and any OEM-specific markings are already in place.","metaTitle":"Siemens 3VA1340-5EF32-0AA0-ZD00 Circuit Breaker, 400A, 55kA","metaDescription":"Siemens 3VA1340-5EF32-0AA0-ZD00 IEC frame 400 circuit breaker, 3-pole, 400A, Icu=55kA @ 415V.
