Product Description
Lifecycle Status:
The 3VA51 3-Pole Circuit Breaker is designed for low voltage applications, featuring a thermal-magnetic trip unit. With a rated current of 50A, it offers significant protection with a breaking capacity of 25kA at 480V and 14kA at 600Y/347. The device is equipped with a TM240 trip unit, enabling adjustable overload settings ranging from 40A to 50A, and short-circuit protection with an adjustable range of 5 to 10 times the rated current (Ii).
This breaker is constructed without lugs, allowing for streamlined installation with dimensions of 3 x 5.5 x 3.7 inches. It is suitable for mounting on a DIN rail (top hat rail) and has an IP40 degree of protection, making it suitable for various industrial environments.
Furthermore, it includes features such as a built-in device for protection unit and does not integrate an earth fault protection or under voltage release. The device's rated short-circuit breaking capacity at 400V and 50Hz is rated at 36kA. These specifications ensure reliable operation in demanding applications.
