The TM240 thermal-magnetic trip unit gives adjustable overload protection (Ir) from 112 A to 160 A, so you set it to match the continuous load current of the downstream cable or bus. This variant includes a nut keeper kit specified for DC Power OEM assembly in China — that's a panel-builder detail: the kit retains the mounting nuts during transport and vibration, a common requirement for pre-wired power skids shipped to Chinese integrators. Because it's a current-production Siemens 3VA1 frame, the full range of accessories (rotary handles, shunt trips, auxiliary contacts, busbar connectors) is available and documented. No need to stockpile spares for a phase-out. The nut keeper kit means the installer doesn't need to hold nuts from behind during tightening, which speeds assembly on pre-fab panels. Rated 160 A continuous, it's sized for main or large-feeder protection in a 400 V three-phase system — think incoming supply to a sub-distribution board, or a large motor feeder with downstream OL relay coordination.","metaTitle":"Siemens 3VA1116-5EF32-0AA0-ZD00 Circuit Breaker, 160A, 55kA","metaDescription":"Siemens 3VA1116-5EF32-0AA0-ZD00 IEC frame 160 MCCB, 3-pole, 55kA breaking capacity @ 415V, TM240 thermal-magnetic trip, Ir 112-160A.
