7PJ15 High Speed Trip Relay

Description
The 7PJ1521 and 7PJ1524 High Speed Trip relay is a
multi-contact attracted armature relay designed to IEC 60255.
High burden relays with immunity to capacitance discharge
currents. They are also suitable for certain applications where 1.2
they are remote from the initiation signal.
A high burden also permits reliable operation of current oper-
ated series repeat relays. TR relays can be provided with an
instantaneous or time-delayed cut-off.

Benefits
The features of the High Speed Trip Relay are:
• High speed, high burden, positive action, and instantaneous
cutoff.
• The 7PJ1524 trip relay can be used with the Trip Circuit Super-
vision relay (7PJ13) to monitor and supervise the integrity of
the trip circuit with coil supervision terminal.
• It is supplied in a draw-out type case.

[7PJ15_FrontView, 1, --_--]

• Tripping of multiple circuit-breakers

• Tripping and lock out application of feeder and transformer
circuit-breakers
• Control signaling and interlocking
• Inter tripping and remote tripping interface for SCADA

[sc_7PJ15_drawout, 1, --_--]

• The relay has a robust design for a long, reliable service life.
Applications
The high speed trip relay type 7PJ15 is mainly used for all types
of control and protection circuits in power stations and indus-
trial applications, where a higher grade of reliability and high
contact rating is stipulated. The 7PJ15 relay acts as a high speed
element and contact multiplication in tripping and signaling
circuits of protective relays.
The high speed trip relay is used in the following applications:
