It is fitted with an ETU350M electronic trip unit configured for motor protection — LSI curves, with overload protection Ir adjustable from 320 A to 800 A and short-circuit protection Isd from 3 to 15 × Ir. The instantaneous pickup Ii is fixed at 15 × In (800 A). This unit also includes an undervoltage release rated 24 V DC, an accessory that drops the breaker when control voltage is lost. ## Deployment and panel fit The frame 1000 footprint matches standard 3VA2 distribution boards and motor control centers. The undervoltage release is wired to a 24 V DC control circuit; losing that signal trips the breaker, which is the usual arrangement for emergency-stop or undervoltage protection on motor feeders.","metaTitle":"Siemens 3VA2580-5MN32-0BL0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA2580-5MN32-0BL0 IEC frame 1000 MCCB, 3-pole, motor protection ETU350M, In=800A, Icu=55kA @ 415V.
