Industrial Control Relays
Miniature control relays
HH52, 53, 54
Miniature control relays
■ Description
The HH52, 53 and 54 are a series of
miniature general purpose relays
specially designed for users
demanding small size, sturdy
construction and high electrical
capacity. Mechanisms are furnished in
polycarbonate dust-proof enclosures
and are recommended for a multitude
of electrical control applications for
their reliability and compact size.
Continuous duty coils, either AC or DC
are available for voltages up to 240V
AC or 120V DC. Contacts can be
supplied in 2PDT, 3PDT, 4PDT
arrangements. Continuous current
ratings are 3, 5 and 7 Amps. Many
terminal types are available for solder,
plug-in or printed circuit board
mounting.

■ General information
● Contacts
Miniature relays can be supplied with
contacts that meet most electrical and
mechanical contact requirements. The
standard HH52, 53 and 54 series are of
the single contact type as illustrated.
The HH52W (2PDT) and HH54W (4PDT)
relays are supplied with bifurcated
contacts. These bifurcated contacts are
with good conducting characteristics
and are recommended where limited
control power is available.
● Enclosures
All miniature relays are enclosed in
sturdy heat-resistant polycarbonate
covers providing protection against
dust and dirt.

The dielectric strength is 1000 volts rms
50/60Hz (between open contacts) which
makes them more than adequate for
power circuit use.
