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

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

LED flashing indicates that the relay is in the
process of reclosing

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)
