Circuit breakers VA 47-63 4.5 kA EKF PROxima are mechanical switching devices and comply with GOST R50345-2010. The feature of this series of circuit breakers is an improved design. The circuit breakers feature plastic covers that block access to the screw terminal and serve for sealing the circuit breakers, which prevents unauthorized access to the conductors. The circuit breaker housing is reinforced with additional rivets to eliminate the housing separation effect. The circuit breakers are equipped with a convenient operating handle that ensures reliable operation of the products. The front panel of the circuit breakers features a color status indicator. The mounting clip design ensures easy installation of the circuit breaker on a DIN rail.
