Overload protection is via a TM240 thermal-magnetic trip unit, adjustable from 88 A to 125 A (Ir). Short-circuit magnetic pickup (Ii) is fixed at 5 to 10 times In — so on a 125 A frame, that's 625 A to 1250 A instantaneous trip. The nut keeper kit included with the DC Power OEM variant secures the busbar connections on the line side — a detail that matters when the breaker is installed in a China-based OEM panel destined for a DC power distribution system. Verify the busbar pitch matches the 4-pole terminal spacing before final torque.","metaTitle":"Siemens 3VA1112-6EF42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1112-6EF42-0AA0-ZD00 IEC frame 160 circuit breaker, 70kA breaking capacity at 415V, 125A TM240 overload protection.
