Tap-off units for plug-in (125 - 630 A)
-
Tap-off units for plug-in are available for straight busbar elements with
plug-in in protection type IP55. They can be used on straight busbar
elements with plug-in of any rated current.
-
Tap-off units for plug-in with currents up to 630 A can be installed while
operating (without disconnecting the busbar run). However, country-specific
regulations may prohibit connecting to live busbar runs.
-
Tap-off units for plug-in are constructed to fit only one way.
-
They are fitted with an interlock which prevents the units from being plugged
into or being removed from the straight busbar elements while the protection
device is switched on.
Connection compartment for tap-off units
Planning information: Tap-off units for 400 and 630 A plug-in have an extra large
connection compartment. Consequently they can only be fitted to straight busbar
elements with up to 2 plug-in per side.
Dimensions of straight busbar element with 2 plug-in per side
On straight busbar elements with three plug-in on one side, when fully extended
only tap-off units up to a maximum rated current of 250 A are possible.
Dimensions of straight busbar element with 3 tap-off units per side
