That range lets you coordinate selectivity with downstream breakers without oversizing the main. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — figures that put it in the high-interrupting category for industrial mains. At 415 V it clears a 121 kA fault without external fuses, which covers most LV switchgear secondary-side faults. ## Thermal performance and derating That's a wide flat curve — you don't lose headroom in a warm enclosure until you push past 65 °C. Dimensions are 210 mm wide, 320 mm high, 120 mm deep — a standard SENTRON 3VA2 frame size.","metaTitle":"Siemens 3VA2580-5HL32-0KA0 SENTRON MCCB, 800 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2580-5HL32-0KA0 molded case circuit breaker, 800 A rated continuous current, 187 kA breaking at 240 V, ETU320 release.
