Siemens Reyrolle 7PJ15 HIGH SPEED TRIP RELAY

The Siemens Reyrolle 7PJ15 Relay features a multi-contact attracted armature design that complies with IEC 60255 standards. High burden relays with immunity to capacitance discharge currents. They are suitable for applications located remote from the initiation signal. The high burden enables reliable operation of current-operated series repeat relays. Fast operation, high load capacity, reliable performance, and instant cut-off.

Benefits The features of the High Speed Trip Relay are:

• Fast operation, high load capacity, reliable performance, and instant cut-off.
• The 7PJ1524 trip relay works with the Trip Circuit Supervision relay (7PJ13) to monitor and supervise the integrity of the trip circuit through the coil supervision terminal.
• It is supplied in a draw-out type case.

The 7PJ1521 and 7PJ1524 high-speed trip relays feature a multi-contact attracted support structure design that complies with IEC 60255.

The features of the Siemens Reyrolle 7PJ15 RELAY are:

• High-speed, high burden, positive action, and instant cutoff.
• The 7PJ1521 and 7PJ1524 trip relays operate with the Trip Circuit Supervision relay (7PJ13) to monitor and supervise the integrity of the trip circuit through the coil supervision terminal.
• It comes in a removable case.

Functions of Siemens Reyrolle 7PJ15 RELAY

The high-speed trip relay type 7PJ15 mainly supports all types of control and protection circuits in power stations and industrial applications where engineers require a higher grade of reliability and high contact ratings. The 7PJ15 relay works as a fast-paced unit and increases contact output in tripping and signaling circuits of protection relays.

As a result, the high-speed trip relay is suitable for the following applications:

• Tripping of multiple circuit-breakers
• Tripping and lock
• Control, signaling, and locking
• Inter tripping and remote tripping interface for SCADA
