Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — figures that cover most low-voltage distribution fault levels without cascading upstream. The 800 A rating holds flat through 60 °C; at 65 °C it derates to 767 A, and at 70 °C to 703 A, so panel ambient above 60 °C needs a one-frame-up check. ## ETU320 trip unit — adjustable protection bands The ETU320 release gives adjustable long-time pickup (Ir) from 320 A to 800 A, and instantaneous pickup (Ii) from 1,200 A to 8,000 A. Long-time delay (tr) is adjustable between 0.5 and 17 seconds. That range covers feeder and main protection for most 480 V and 690 V distribution panels without needing a separate relay. Front face carries IP40 protection; the enclosure is designed for panel-mount installation with line and load connections accessible from the front.","metaTitle":"Siemens 3VA2580-5HL32-0AG0 SENTRON MCCB, 800 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2580-5HL32-0AG0 molded case circuit breaker, 800 A continuous, 3-pole, ETU320 release, 187 kA at 240 V.
