The ETU860 gives adjustable long-time pickup (Ir) up to 800 A and short-time delay (tsd) from 0.05 s to 0.5 s, letting you coordinate selectively downstream. It carries a communication function for remote monitoring or trip-event capture, and ground-fault monitoring via summation-current formation on the line conductor. ## Sizing into the panel — footprint and thermal derating The breaker measures 210 mm wide by 320 mm tall by 120 mm deep. That 210 mm width means it occupies three full 70 mm pole spaces on a standard DIN-rail or panel-mount backplate — verify your enclosure's gland-plate fill before committing the cutout. At 40 °C through 60 °C ambient the 800 A rating holds flat; at 65 °C it derates to 767 A, at 70 °C to 703 A.","metaTitle":"Siemens 3VA2580-5KQ32-0CL0 SENTRON MCCB, 800 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2580-5KQ32-0CL0 molded case circuit breaker, 800 A rated, 187 kA breaking at 240 V.
