It uses a TM220 thermal-magnetic trip unit with adjustable overload protection (Ir = 35 A to 50 A) and fixed short-circuit protection set at Ii = 10 x In. The N conductor is unprotected, and the unit includes a nut keeper kit for DC Power OEM applications in China. The adjustable overload range (Ir = 35 A to 50 A) lets you fine-tune the trip point to the actual load, while the fixed short-circuit setting at 10 x In (500 A) provides a defined magnetic trip threshold. The unprotected N conductor signals that the neutral is not switched or monitored, which is standard for many 4-pole line-side configurations. ## Deployment Context This breaker mounts on a DIN rail in a standard IEC enclosure, sized for panel integration in OEM equipment or distribution boards. The nut keeper kit is specific to DC Power OEM builds in China, so verify the mounting hardware matches your panel layout.","metaTitle":"Siemens 3VA1150-4EE42-0AA0-ZD00 Circuit Breaker, 50A, 36kA @","metaDescription":"Siemens 3VA1150-4EE42-0AA0-ZD00 IEC frame 160 circuit breaker, 50A, 36kA breaking capacity @ 415V.
