The 3VA51 circuit breaker operates within a rated voltage of 690V and provides effective line protection through its three poles, rated at 45A. It incorporates a thermal-magnetic trip unit, specifically model TM230, which offers fixed overload protection set at 45A and adjustable short-circuit protection ranging from 5 to 10 times the nominal current (Ii). The device stands out with its medium breaking capacity (Class M) of 35kA at 480V and 18kAIC at 600Y/347.
Designed without lugs, this circuit breaker is suitable for naval applications and can operate in environments with temperatures up to 50°C. It measures 3 inches in width, 5.5 inches in height, and 3.7 inches in depth. Additionally, it features a rocker lever as the control element and is compatible with DIN rail (top hat rail) mounting.
Country of origin is CZ, and the device is constructed as a built-in device using fixed built-in techniques. Notably, it does not include integrated earth fault protection or an under-voltage release, but it is a complete device with a protection unit.
