UL1059 & CSA 22.2 No. 158 Voltage Rating
Voltage ratings of terminal blocks are based on the
minimum spacing between electrically conductive parts
and a minimum withstand voltage. The spacings are
measured under two conditions: 1) through air, defined as
the shortest distance an arc must travel through an air
path from one electrically conductive part to another at
opposite polarity or from an electrically conductive part to
a grounded surface; and 2) over surface, defined as the
shortest distance an arc must travel as it tracks along the
surface of an insulating material from one electrically
conductive part to another at opposite polarity or from an
electrically conductive part to a grounded surface. The
withstand voltage, termed dielectric withstand, is
dependent on the voltage rating. The value is 1000V plus
twice the rated voltage for one minute. this is tested under
both conditions listed above. The following chart shows
the UL 1059 and CSA 22.2 No. 158 spacing requirements,
in inches.
IEC Compliance
Some Magnum Terminal Blocks comply with the
requirements in IEC Publication 60947-7-1 Terminal Blocks
for Copper Conductors. these blocks are concurrently
recognized and certified under the UL Classification
Program. Ratings, except where indicated, are concurrent
with UL 1059.
CE
In 1998, Cooper Bussmann received CE certification on
all Magnum products. For terminal blocks, CE is a
self-certification mark applied to products that have met
safety and performance requirements set forth by the
European Union (EU). This mark is required for free
movement of product in the European market.
