It's a 4-pole unit with line protection via a TM220 thermal-magnetic trip. Overload protection (Ir) is adjustable from 18 A to 25 A; short-circuit protection (Ii) is fixed at 12.8 times In, so about 320 A magnetic pickup. That's a steep magnetic ratio — good for high-inrush loads like transformers or DC drives where you don't want nuisance trips on startup. ## Sourcing & Fit The nut keeper kit and DC Power OEM designation suggest this variant was configured for a specific Chinese OEM contract. That doesn't affect fit for general distribution — the base 3VA1 frame, trip curve, and interrupt rating are standard IEC catalog items. If you're replacing an existing unit, verify the accessory kit matches your panel's hardware.","metaTitle":"Siemens 3VA1125-6GE42-0AA0-ZD00 3VA1 IEC Frame 160 Breaker,","metaDescription":"Siemens 3VA1125-6GE42-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 160, breaking capacity class H Icu=70kA @ 415V, 4-pole, In=25A, TM220 overload protection.
