It carries a TM240 thermal-magnetic trip unit with adjustable overload protection (Ir) from 35 A to 50 A and short-circuit protection (Ii) set at 5 to 10 times In. The N-conductor is fully protected (100% rating), and the unit includes a nut keeper kit — a variant built for DC Power OEM supply into China. Lifecycle status is listed as current, meaning Siemens has not flagged this order code for discontinuation. It remains a standard catalog item within the 3VA1 platform. The TM240 trip unit gives you a thermal-magnetic curve: the thermal element handles overloads (Ir adjustable 35–50 A), and the magnetic element handles short-circuits (Ii adjustable 5–10× In). The 4-pole design with 100% N-conductor protection means the neutral pole is not just a switched pole but fully protected against overload — critical for line-to-neutral faults in a 4-wire system. The nut keeper kit is a mechanical accessory for secure mounting in DC Power OEM panels.","metaTitle":"Siemens 3VA1150-4GF42-0AA0-ZD00 Circuit Breaker, 50A, 36kA @","metaDescription":"Siemens 3VA1150-4GF42-0AA0-ZD00 IEC frame 160 circuit breaker, 50A, 36kA breaking capacity @ 415V, 4-pole, TM240.
