The 200 A continuous rating holds flat from 40 °C through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. The 800 V rated insulation voltage (Ui) means it can be used on 480/277 V and 600 V systems with margin; the 690 V interrupting rating confirms it handles 600 V class installations. The undervoltage release (UVR) is built in; if the control voltage drops, the breaker trips — common for emergency-stop circuits or undervoltage protection on motor starters. No communication function or ground-fault monitoring on this variant, so it's a straight thermal-magnetic breaker with UVR and auxiliary contacts.","metaTitle":"Siemens 3VA1220-4EF32-0DC0 SENTRON MCCB, 200 A, 121 kA at 24","metaDescription":"Siemens SENTRON 3VA1220-4EF32-0DC0 molded case circuit breaker, 3-pole, 200 A rated continuous current, 121 kA breaking capacity at 240 V.
