Product Overview
The VL1250N breaker provides standard breaking capacity with a rated ultimate short-circuit breaking capacity of 55 kA at 415 V AC. Its ETU10 trip unit delivers long-time overload and instantaneous short-circuit protection for a three-pole line-protection application.
The rated current is 1250 A, with the long-time setting adjustable from 500 to 1250 A and the instantaneous setting adjustable from 1.25 to 10 times rated current. The official configuration lists no auxiliary release and no auxiliary or alarm switch.
Key Functions
Line Protection
The three-pole breaker provides overload and instantaneous short-circuit protection through an ETU10 LI trip unit.
Adjustable Overload Protection
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.
Standard Breaking Capacity
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.
