The WMS series has been discontinued. Please see the UL 489 series as a possible alternative or contact our Automation Engineering department.
Offering maximum reliability and accuracy,
the supplementary protectors fit various
applications where a fuse may have been
previously used. The advantage over fuses is
that it is resettable and the device’s status is
easily and clearly identified by the position of
the handle and the flag indicator. With easy
mounting of the device on a 35 mm (1.38")
DIN rail it is now easier for the customer to
select and apply this modular range, due to
the smaller modular width of the device and
accessories.
The WMS supplementary
protector is a dual-rated product for both AC
and DC supplies, in accordance with UL
1077, CSA 22.2 and IEC 898 standards and
is marked with CE in accordance with the
Low Voltage Directive. With this dual
standard product, you can include it within
your design, knowing that, in the vast
majority of cases wherever the equipment is
used, the product is in line with the local UL,
CSA or IEC (European) requirements. This is
very important as the different areas of the
world market draw closer together and the
need for breakers that meet different
standards is a common, everyday
occurrence. It is to be applied in conjunction
with a branch protector (if branch protection
is required) and can be a replacement for
similarly applied fuses. In addition to this,
you are able to select a device that provides
maximum reliability and accuracy to fit their
various applications (of which there are
many) due to the availability of a wide range
of current ratings from 0.5 to 60 amperes
and three different overcurrent characteristic
curves.
With easy mounting of the device on
a 35 mm (1.38") DIN-rail and also the “Quick
3 Step” field mountable accessories, it is
now easier to select and apply this modular
range. In addition, utilizing the bus bar comb
to connect multiple devices from a single
power source, saves time as multiple wire
connections are no longer required. Due to
the smaller modular width of the device and
accessories, it enables them to save space in
their panel or equipment—which directly
leads to cost savings!
