Katko-NHP solar isolators
recalled due to risk of fire
All Katko-NHP brand solar isolator
switches have been recalled due to an
internal fault posing a risk of fire and
electric shock.
The recall includes all KDA-432 and
KDM-432 type products including those
replaced as a result of a previous recall in
February 2014. The recall in February 2014 was
on the same product but for a different fault.
The affected units were sold to
electrical contractors or solar contractors
and installers between July 2013 and
October 2014.
The switch contact mechanism in the
affected products may overheat due to an
internal fault, potentially causing damage to
switch mechanism, enclosure and cables
and resulting in access to live parts
and internal arcing.
All KDA-432 and KDM-432 products
are required to be replaced. PV systems
with these switches should be shut down
and safe isolation procedures need to
be followed.
Homeowners should contact the
electrical contractor as soon as possible
to organise for the replacement of any
affected switches. Re-sellers should cease
supplying these switches and arrange to
return them to NHP.
