The breaking capacity hits 55 kA at 415 V — that's class M in the 3VA1 lineup, meaning it handles high fault currents common in industrial distribution without needing an upstream fuse to back it up. That's enough for most 415 V industrial switchboards downstream of a transformer — you get full selectivity without stepping up to a larger frame. The TM210 thermal-magnetic trip gives you an adjustable thermal curve (Ir fixed here at 50 A) and a fixed magnetic pickup at 500 A. That fixed short-circuit protection means no dial to accidentally bump, which matters on a line where the breaker sits in a panel for years. The N conductor is unprotected on this variant — it passes through without overcurrent protection. That's a deliberate choice for delta or corner-grounded systems where the neutral doesn't carry fault current. The nut keeper kit is specified for DC Power OEM builds in China, so if you're integrating this into a DC bus or inverter-fed panel, the hardware matches that assembly standard.","metaTitle":"Siemens 3VA1150-5ED42-0AA0-ZD00 Circuit Breaker, 50A, 55kA @","metaDescription":"Siemens 3VA1150-5ED42-0AA0-ZD00 IEC frame 160 circuit breaker, 4-pole, 50A, 55kA breaking capacity @ 415V.
