Finder’s 77 Series ‘single pole’ solid
state relays are available in eight new
versions, with a 30A current rating to
complement the existing 5A models.

With models for zero-voltage and
instantaneous switch-on, the former
is suitable for lighting control
where zero-voltage switching
can reduce high inrush
currents. Instantaneous
switch-on provides near
instant switching for high
speed operation and
simultaneous switching in
multi-phase circuits, such
as three phase motors.

The high inrush current
capability of 520A (10ms)
ensures reliability over a long life in a
wide range of applications.

In 22.5mm housing incorporating
the heat sink and designed for 35mm
rail mounting, the relays are suitable
for use in control panels and cabinets
in industrial and commercial
applications.
