The N-conductor protection is set to 100%, meaning the neutral pole is fully protected at the same rating as the phase poles — important for 4-wire systems where neutral current can approach phase current. The In=50 A rating with an adjustable Ir range of 35 A to 50 A means this breaker covers a motor or feeder load that draws between those values. You dial in the exact continuous current with the thermal adjustment, so one breaker body covers a range of load sizes — good for stocking flexibility. The Ii adjustment from 5x to 10x In (250 A to 500 A) lets you tune the magnetic pickup to avoid nuisance trips on inrush while still clearing a hard fault. The IEC frame 160 footprint is standard for Siemens 3VA1 accessories and busbar systems.","metaTitle":"Siemens 3VA1150-3GF42-0AA0-ZD00 Circuit Breaker, 50A, 25kA @","metaDescription":"Siemens 3VA1150-3GF42-0AA0-ZD00 IEC frame 160 circuit breaker, 50A, 25kA breaking capacity @ 415V, 4-pole.
