The TM220 thermal-magnetic trip unit provides overload protection adjustable from 88 A to 125 A (Ir) and a fixed short-circuit pickup of 10 x In (Ii = 1250 A). The 100% N conductor protection means the neutral pole is fully rated and trips simultaneously with the phase poles — required on 4-wire systems where the neutral carries unbalanced load current and must be switched, not just connected. The ATFM designation indicates the trip unit is adjustable thermal, fixed magnetic. ## OEM variant and deployment context This order code carries the -ZD00 suffix, a Siemens OEM variant configured for DC Power applications in China. The 4-pole form factor suits it for three-phase + neutral distribution panels, UPS output breakers, or generator paralleling gear where neutral switching and protection are mandatory. The 70 kA class H rating gives selectivity headroom downstream of a larger main breaker. No spare, no sleep — this one is worth keeping one in the cabinet if the install is remote or the line has no redundancy.","metaTitle":"Siemens 3VA1112-6GE42-0AA0-ZD00 125A 70kA 4P MCCB","metaDescription":"Siemens 3VA1112-6GE42-0AA0-ZD00 circuit breaker, 125A, 70kA @ 415V, 4-pole, TM220 thermal-magnetic trip, 100% N protection.
