The Siemens 3VA1150-3GD42-0AA0-ZD00 is a 4-pole molded case circuit breaker (MCCB) on the IEC 3VA1 frame. It is rated for line protection with a TM210 thermal-magnetic trip unit, fixed at In=50A overload protection (Ir=50A) and short-circuit protection set at Ii=10 x In. The breaking capacity class N delivers an Icu of 25kA at 415V, which is the fault current it can safely interrupt without upstream damage — a figure that governs panel SCCR coordination. This variant includes 100% N-conductor protection and a nut keeper kit for DC Power OEM applications in China.
