The TM210 release has an adjustable magnetic trip (li) up to 800 A, so you can tune the instantaneous pickup for motor inrush or cable protection without swapping the breaker. No communication function on this variant, no motor drive, no ground-fault monitoring — it is a straight line-protection MCCB.","metaTitle":"Siemens 3VA1080-4ED46-0AA0 SENTRON MCCB, 80 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1080-4ED46-0AA0 molded case circuit breaker, 80 A, 4-pole, TM210 release, 121 kA at 240 V.
