It carries a thermal-magnetic TM220 trip unit with adjustable overload protection (Ir) from 35 A to 50 A and fixed short-circuit protection set at 10 times In. The N conductor is unprotected, and the breaker includes a nut keeper kit; this variant is configured for DC Power OEM supply in China. The adjustable thermal overload (Ir = 35–50 A) lets you match the breaker to the actual continuous load, while the fixed magnetic trip at 10× In (500 A) clears hard shorts fast. The unprotected N conductor means this is a 3-pole protected + solid neutral configuration; verify the system grounding scheme before specifying. ## Deployment context The nut keeper kit simplifies busbar or cable lug termination in high-vibration environments. The DC Power OEM designation flags that this variant is configured for DC-side protection in power supply or battery applications — confirm polarity and DC voltage rating before installation.","metaTitle":"Siemens 3VA1150-3EE42-0AA0-ZD00 Circuit Breaker, 50A, 25kA","metaDescription":"Siemens 3VA1150-3EE42-0AA0-ZD00 IEC frame 160 circuit breaker, 50A rated, 25kA breaking capacity at 415V.
