It's a 4-pole unit with line protection via a TM210 thermal-magnetic trip unit; overload protection is fixed at Ir=25A and short-circuit protection is fixed at Ii=12.8 x In (320A). This breaker mounts into a standard Siemens 3VA1 panelboard or distribution board — the IEC frame 160 footprint is common across the 3VA1 line. The nut keeper kit is a nice touch for OEM panel builders in China: it keeps the busbar connection hardware captive during assembly, saving time on the line.","metaTitle":"Siemens 3VA1125-6ED42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1125-6ED42-0AA0-ZD00 IEC frame 160 breaker, Icu=70kA @ 415V, 4-pole, TM210, In=25A, Ir=25A, Ii=12.8 x In.
