RKF-3/1M
The block of the relay of control of the phases RKF-3/1-M is intended for control of work of a three-phase network by means of the microprocessor and the organization of system of protection of three-phase loadings against emergencies in a network by means of the external actuation mechanism.
Design
The block RKF-3/1-Mvypolnen in the case for installation on a DIN lath.
On the forward panel of the block there are NETWORK and ACCIDENT indicator.
In the lower and top part of the block of the relay of control of phases there are terminal blocks for connection of the block to a network and to the scheme of management. Power supply of the relay is carried out directly from a controlled network.
Warranty period – 2 years.
