Features
• Small package design
• Silver Cadmium Oxide gold flashed contact
• High open contact dielectric strength
(1,000 VAC)
• High reliability and long life
• High vibration and shock resistance
LED indicator on all models, so you can easi-
ly see if the RELAY is working properly with-
out using a voltmeter
• Flag indicator shows RELAY status in manual
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
push button and contacts in the operate
position allowing circuits to be analyzed.
This feature is not available on 781 series.

The 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
electric control panels requiring stable and
reliable RELAYs
SPDT 2PDT, 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
