OPERATION
Features of the RRM as an overload/short circuit
reclosure device
No. of reclosures: Programmable (0, 1, 2, 4, 6, 8
Time between reclosures
Programmable (0.5, 1, 2, 3, 4, 5 minutes
ime to return to zero: 30 minutes
The RRM relay is associated with the MT series,
motorised overload/short circuit breakers.

No. of reclosures.
ime between reclosures
Remote control. The disconnection or reclosure of
the automatic switch may be forced using a potential
free input or using a 230 V AC. voltage. (When this
contact is closed, the switch cannot be reclosed).
When the relay reclosure is already sealed the remote
control doesn´t act

DESCRIPTION.
Button description
Rearm of the sealed relay and/or returning to
zero of the internal reclosure counters
Only on model RRM-C. Pressing sends
voltage to the relay, it is started with the
address no. 1 in the RS485 system.
Switch description
Select the number of reclosures: 0, 1, 2, 4, 6,
8. Position zero cancels the motorised circuit
breaker reclosures
Select the time between reclosures in units of
minutes: 0.5, 1, 2, 3, 4, 5
On site signalling using LEDs
Display LED description
Indicates that the relay is being supplied and
the overload/short circuit breaker protection
is not tripped. Green LED.
Overload/short circuit breaker on OFF as
default
LED constantly on indicates that the relay
reclosure is sealed
LED flashing indicates that the relay is in the
process of reclosing
Overload/short circuit breaker on OFF

INTRODUCTION
The RRM range of relays allows the control, remote
signalling and control of the associated motorized circuit
breaker (MT SERIES)
The functions of the RRM relay are
Control of the motorized overload/short circuit
protection
Self reclosing
Remote disconnection/connection (not
reconnectable)
Signalling:
On site using LEDs
Remote signalling using relay, of the reclosure
seal in model RRM-P
RS485 Communications in model RRM-C
Remote control of the automatic switch
The self reclosing equipment for DIN rail consists of
Motorised, MT type overload/short circuit
protectors (2 or 4 pole)
