RMT/1

DESCRIPTION
Earth fault definite time residual current relay with 1 operation threshold.
The device is supplied in a 48x48 mm panel mounting housing with plastic frontal cover.
The relay is made with a high immunity level against electrical disturbances so that it is particularly suitable, along with the small size, for assembly into modular elements of MCC and PMCC.

RMT/2

DESCRIPTION
Earth fault definite time residual current relay with 1 operation threshold.
The device is supplied in a 72x72mm panel mounting housing with sealing frontal plastic cover in order to prevent infringements to the setting.
The relay is made with a high immunity level against electrical disturbances so that is particulary suitable, along with the small size, for assembly into modular elements of MCC and PMCC.

OPTIONS
* 3...300A setting range: type RMT/2B

RMT/3

DESCRIPTION

Earth fault definite time residual current relay with 1 operation threshold.
The device is supplied in a 96x96 mm reduced dept case for panel mounting, with sealable transparent plastic cover in order to prevent infringements to the setting.

RMT/4

DESCRIPTION
Earth fault definite time residual current relay with 1 alarm threshold and 1 operation delayed threshold. Thanks to the warning threshold alarm, the relay is suitable for those plants where preserving service continuity or minimizing the risk of equipment damage is the more important objective. Additional interesting feature is the circuit breaker trip circuit supervision (TCS), driving a normally energized final relay (SELF). The device is supplied in a 96x96 mm reducent dept case for panel mounting with a sealable transparent plastic cover in order to prevent infringements to the setting.

OPTIONS
* Mechanical flag indication for relay tips: type RMT/4M
* 3...300A setting range: type RMT/4B

RMT/3D


DESCRIPTION

Earth fault definite time residual current relay with 1 operation threshold. The device is supplied in a 4 modules case for standard DIN rail mounting with a sealable transparent plastic cover in order to prevent infringements to the settings.

DESCRIPTION

Digital indicator of istantaneous earth current for earth differential relays.
The input is taken from wiring between earth fault relay and ring toroidal transformer.
Case for mounting on standard DIN rail.

PT1 - PT2


DESCRIPTION

PT1

Earth fault definite time residual current relay with 1 operation threshold with toroidal transformer mounted in the same case of the relay; its employement is peculiar for motor feeders. The device is made with a high immunity level against electrical disturbances so that it is particularly suitable, along with small size and mounting system, for assembly into modular elements of MCC and PMCC.

PT2

Earth fault definite time residual current relay with the same characteristics of a.m. PT1 with the additional of a second change over contact for telecontrol systems.

OPTIONS
* Repeating signal device RPT

PT3 - PT4

DESCRIPTION

PT3

Earth fault definite time residual current relay with 1 operation threshold and for coupling with a separate toroidal transformer; its employement is peculiar for motor feeders. The device is made with a high immunity level against electrical disturbances so that it is particularly suitable, along with small size and mounting system for assembly into modular elements of MCC and PMCC.

PT4

Earth fault definite time residual current relay with 1 alarm threshold and 1 operation threshold with toroidal transformer mounted in the same case of the relay; its employement is peculiar for motor feeders.
The unit is made with a high immunity level against electrical disturbances so that it is particularly suitable, along with small size and mounting system, for assembly into modular elements of MCC and PMCC.
