Tightening Torque
To find a current rating, place
a straight edge horizontally at
the value of anticipated
maximum internal panel
ambient (scale on the left),
and read the current rating for
the device on the bottom
scale. Example: at 60°C,
TBAT3 is rated 54 amperes.
Ampere rating is based
on maximum allowable
temperature—ambient
temperature plus
temperature rise due
to current.
Ratings based on 90°C total
temperature of a three-pole
block with each pole carrying
current and wired with largest
size conductors.
