RPDF Unbalance and Phase Failure Relays
The RPDF-electronic relay is intended for the protection of lines or electronic motors
against unbalance between phases or failure of one or more phases. Detection of
unbalance or phase failure is done by measuring phase change and not by voltage
levels. This guarantees proper operation even when there are return paths due to
motors running which are connected to the main network to be protected.
The relay is made when all conditions are normal (contact 11-14 closed); the contacts
open in the event of a failure. In this way, any failure, including that of the relay supply
voltage, will cause disconnection and prevent the supply from being left unprotected.
Setting unbalance
The unbalance of phases is a limiting factor in the life of an electric motor. The graph
below right shows the percentage temperature increase in a three-phase motor as a
function of the degree of unbalance (See standards NEMA MG 1-1433 and 34).
The percent unbalance is calculated as follows:
Section 10Logic Control
% unbalance = x 100
max. voltage deviation from average voltage
average voltage
Tripping is adjustable between 2.5 and 10%. Consequently protection is provided for
motors working closely adjusted to rated power, to others more generously sized, and
even power lines. In any case adjustments should be made so that on failure of one
phase, the relay will disconnect.

RMM 2 Maximum and Minimum Voltage Protection (Three Phase) Relays
These voltage-sensitive relays with two selectable output contacts remain closed (contact between 11-14 or between 21-24) when voltage is within tolerance limits, and open
when voltage surpasses these limits. The relays can be used to detect low or over voltage in balanced single or three-phase systems, and maximum and minimum tripping
values are adjustable by means of two potentiometers.

RS01N Thermistor Relays
This thermal probe relay is sensitive to the resistance of several thermal probes (thermistors,
RTD) connected to P1 and P2 and defects overheating in motor windings, transformers, etc.
The relay disconnects when probe resistance exceeds 2500 ohms and cannot reset until
resistance is lower than 1500 ohms. The absence of control voltage to the A1 and A2
terminals causes the relay to trip. When the relay trips due to motor overheating it can
be reset either manually, automatically or remotely.
The RS01N detects those cases of shortcircuited probe cables (resistance lower than 20
ohms) or cut probe cables (resistance higher than 2.5 k ohms). The resistance at 77°C of
the probe circuit must be within a range of 40 to 600 ohms.

RCF-1 Frequency Control Relays
The frequency control relay is sensitive to the frequency of the signal applied to terminals
B1 and B2. The output contacts close when the frequency falls below the selected
threshold (adjustable by potentiometer).
There are three frequency setting ranges: 5-15 Hz, 15-45 Hz, 45-135 Hz. Switching is
independent of the input signal’s amplitude being monitored at B1-B2. The signal’s wave
form can be sinusoidal, square, triangular, etc. This relay is suitable for suppression of
rotor resistance in slip-ring asynchronous motor starters, speed reversal detector in
wound rotor motors and frequency control in generating sets.
