Siemens Reyrolle 7PJ15 HIGH SPEED TRIP RELAY

Product Description

The 7PJ1521 and 7PJ1524 High Speed Trip relay is amulti-contact attracted armature relay designed to IEC 60255. High burdenrelays with immunity to capacitance discharge currents. They are also suitablefor certain applications where they are remote from the initiation signal. Ahigh burden also permits reliable operation of current operated series repeatrelays. TR relays can be provided with an instantaneous or time-delayedcut-off. Benefits The features of the High Speed Trip Relay are: • High speed, highburden, positive action, and instantaneous cutoff.

ʉۢ The 7PJ1524 triprelay can be used with the Trip Circuit Supervision relay (7PJ13) to monitorand supervise the integrity of the trip circuit with coil supervision terminal.

• It is supplied in a draw-out type case.
