High Speed Tripping Relay TR

Description Features

Figure 1: High Speed Tripping Relay - TR

• High speed, positive action• Robust design for long, reliable service life• Supplied in Epsilon draw-out type case• Can be supplied both in E2 and E4 casing

Type TR high speed tripping 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.

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.

High Burden, TR2 SeriesHigh burden relays have 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.

Technical InformationTR1 and TR2 series relays

Rated Voltage, Vn 24V, 30V, 48V, 110V, 220V DC

Operating Range 50% to 120% of Vn

Operating Time 10 ms at Vn

Operating coils of self-reset and economy cut-off relays are rated at 120% of rated voltage. All other operate and reset coils are short time rated, well in excess of the operating time of their cut off contacts. Self-reset relays will reset at not less than 5% rated voltage.
