It carries a TM240 line protection trip unit, set at In=25A, with overload protection adjustable from Ir=18A to 25A and short-circuit protection Ii adjustable from 6.4 to 12.8 times In. The suffix ZD00 adds a nut keeper kit, configured for a DC Power OEM in China. The TM240 thermal-magnetic trip unit provides line protection for cable and busbar systems, not motor overload curves. The adjustable Ir (18-25A) lets you fine-tune the continuous current rating to match the downstream load, while the Ii range (6.4-12.8x In) sets the magnetic short-circuit pickup. The 3-pole configuration suits three-phase power distribution in industrial panels or OEM equipment. ## Deployment Context The nut keeper kit (ZD00 suffix) is for an OEM assembly.","metaTitle":"Siemens 3VA1125-5EF32-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1125-5EF32-0AA0-ZD00 IEC frame 160 circuit breaker, 55kA Icu @ 415V, 3-pole, In=25A, TM240.
