Siemens Reyrolle 7PG15 Tripping Relays

The range comprises electro-mechanical relays for a range of auxiliary and tripping functions. Various combinations of coils, contacts, operation indicator flags can be specified. Options are also available for operate and reset modes. Reyrolle 7PG15 Tripping Relays – High-speed multi-contact tripping relays, available in both high and low burden models. Variants up to 11 contacts, <10 ms operation.

Features

Type TR relays are a range of multi-contact attracted armature relays complying with IEC 61850. A wide range of models is available to meet the requirements of the electric supply industry. High speed, positive action can be supplied in modular and a withdrawable type case. Robust design for a long, reliable service life. Available with up to 20 contacts.

Functions

  • Low burden, TR1 series Type TR1 relays are suitable for application for tripping and auxiliary duties where immunity to capacitance discharge is not required. These relays are not intended for use with current operated series follower relays.
  • High burden, TR2 series High burden relays with immunity to capacitance discharge currents. They are also suitable for certain applications where they are remote from the initiation signal. A high burden also permits reliable operation of current operated series repeat relays. TR relays can be provided with an instantaneous or time-delayed cut-off.
  • Low burden relay, TR312 Designed to meet the requirements of NGC specification P15, this is an electrically reset relay (no flag indicator) with additional terminals in the economy circuit to enable a direct connection to the dc supply. This arrangement allows a reduction in the break duty of the initiating contact.
  • Switching Relay, TR431 Designed to meet the requirements of NGC TDM 5/11, this is an electrically reset relay with a flag indicator which follows the contact operation. These relays are intended to switch protection and auto reclose equipment in and out of service when controlled over pilot wires from a remote point. They are intended to operate from a remote 50V d.c. battery with a pilot loop resistance of up to 200 ohms.

The comprehensive range of Reyrolle products provides the total protection requirements of distribution markets and industrial applications – ranging from overcurrent protection via transformer protection and voltage control to a full spectrum of auxiliary and trip relays.
