VA 47-63 4.5 kA EKF PROxima circuit breakers are mechanical switching devices and comply with GOST R50345-2010. A feature of this series of circuit breakers is the improved design. The circuit breakers have 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 has a color status indicator. The design of the mounting terminal ensures free installation of the circuit breaker on a DIN rail.
