RKF-MP
The module of the relay of control of the phases RKF-MP (further in the text the module RKF-MP) is intended
for: control of tension of a three-phase network 380/220 B with the removed neutral,
managements of operation of the three-phase asynchronous electric motor, control
serviceability of the electric motor before giving of tension on it. Is established in
control panels systems of ventilation, fire extinguishing and smoke removal.
The module RKF-MPl is executed in the case for installation on a DIN lath.
On the forward panel of the block are handles of regulators of installation of an operating mode of the relay and indicators of a condition of a network and electric motor.
Connection of the module to the controllable (feeding) network and to the scheme of management it is carried out through terminal blocks in top and lower part of the case.
