High Speed Tripping Relay TR
The policy of Easun Reyrolle is one of continuous improvement and development. The company therefore reserves the right to supply equipment,
which may differ slightly from that described and illustrated in this publication.
Description
Type TR relays are a range of voltage operated, multi-contact,
attracted-armature relays, complying with the appropriate
requirements of IEC 60255. A wide range of models is available
to meet the requirements of the electrical power sector.
The relays are identified by the product designation ‘TR’ followed
by a series of numbers and letters which define important relay
features as follows:
First Digit Second Digit Third Digit
Type of Contact Reset Operating Coil
Burden Cut-Off
1 Low 1 Self-Reset 1 Instantaneous
2 High 2 Hand-Reset 2 Economy
3 Electrical-Reset
4 Hand &
Electrical-Reset
Low Burden, TR1 SeriesType 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 flag relays.
Features• High speed, positive action
• Robust design for a long, reliable service life
• Supplied in vedette draw-out type case

• Contact arrangement
• Coil voltage
Qualification
ISO 9001-2000
High Burden, TR2 seriesHigh burden relays with immunity to capacitance discharge
currents. They are also suitable for certain application where
they are remote from the initiation signal.
A high burden also permits reliable operation of current operated
series repeat relays.
