The thermal-magnetic trip (TM240, ATAM) gives adjustable overload protection from 56 A to 80 A via the Ir dial, and fixed short-circuit pickup at 5 to 10 times In (400 A to 800 A). The nut keeper kit and DC Power OEM designation suggest this variant was built for a specific DC-power OEM assembly in China; the nut keeper retains the busbar connection hardware during vibration or transport. ## Deployment context Mounts in a standard IEC panel on a DIN rail or screw-fixed backplate — the 160 A frame size is common for main or feeder breakers in industrial distribution boards. The 4-pole configuration suits three-phase systems with a switched neutral, though the unprotected N means the neutral is a pass-through bus, not a switched pole. The nut keeper kit is a small but important detail for panel builders: it prevents the busbar connection from loosening under thermal cycling or shipping vibration, which is a common failure point in OEM assemblies shipped long distances.","metaTitle":"Siemens 3VA1180-5EF42-0AA0-ZD00 IEC Frame 160 Breaker, 55 kA","metaDescription":"Siemens 3VA1180-5EF42-0AA0-ZD00 circuit breaker, IEC frame 160, class M, Icu=55 kA @ 415 V, 4-pole, In=80 A, TM240 ATAM.
