The fixed magnetic trip at 12.8 × In (320 A) is set for motor-start or high-inrush applications; it clears hard shorts fast without needing a separate instantaneous adjustment.","metaTitle":"Siemens 3VM1125-5EE36-0AA2 Circuit Breaker, 55kA @ 415V, 25A","metaDescription":"Siemens 3VM1125-5EE36-0AA2 IEC 3VM1 frame 160 MCCB, 55kA breaking capacity at 415V, 3-pole, 25A adjustable thermal-magnetic protection.
