These ice cube style relays are power

relays designed for applications

demanding high power control in various

factory machines and control panels.

They are ideal for electrical control panels

requiring stable and reliable relays.

Features

• Small package design

• Silver Cadmium Oxide gold flashed con-

tact

• High open contact dielectric strength

(up to 2500V rms)

• High reliability and long life

• High vibration and shock resistance

• LED indicator on all models, so you can

easily see if the relay is working properly

without using a voltmeter

• Flag indicator shows relay status in manu-

al or powered condition

• A pushbutton allows manual operation of

the relay without the need for power to

the coil

• Lock-Down door, when activated, holds

pushbutton and contacts in the “operate”

position, allowing circuits to be analyzed.

This feature is not available on 781

series.

• SPDT, DPDT, 3PDT and 4PDT models

• Finger grip cover allows easier removal

of relays from sockets than conventional

relays

• I.D. tag/write labels for identifying relays

in multi-relay circuits
