Productum Overview
Interruptor VL1250N praebet capacitatem interrumpendi standardem cum capacitate interrumpendi ultimae curtocircuitus nominali de 55 kA ad 415 V AC. Unitas trip ETU10 eius praebet protectionem contra sobrecurrentem longi temporis et contra curtocircuitum instantaneum pro applicatione protectionis lineae tri-polaris.
Currentis nominalis est 1250 A, cum reglamento longi temporis variabili ab 500 usque ad 1250 A et reglamento instantaneo variabili ab 1,25 usque ad 10 vicibus currentis nominalis. In officiali configuratione nullum release auxiliare, nullum interruptorem auxiliarem aut alarmam enumeratur.
Functiones Principales
Linea Protectionis
Interruptor tri-polaris praebet protectionem contra sobrecurrentem et contra curtocircuitum instantaneum per unitatem trip ETU10 LI.
Protectio contra Supersarcinam Regulabilis
The long-time current setting is adjustable from 500 to 1250 A for the documented 1250 A rated-current frame.
Adjustable Instantaneous Trip
The instantaneous short-circuit setting can be adjusted from 1.25 to 10 times rated current.
Capacitas interrumpendi standard
The official product data specifies 55 kA ultimate short-circuit breaking capacity at 415 V AC.
Accessory Configuration Control
The listed configuration has no auxiliary release and no auxiliary or alarm switch, so field accessories must be verified separately.
