This value corresponds to the switch/disconnect capacity, to the power distribution bus bar system capacity (if used) and to the protection circuit capacity in the standard
unit.
**
If the short-circuit current is higher, the unit can be protected by the fuse shown for the specific level.
The fuses (not supplied for Carrier units) are as recommended, to be installed upstream of the unit.
For unit sizes 040 to 160 a fused disconnect switch, equipped with fuses, can be installed in place of the standard unit switch. This should be done on site; please
contact the local service department or a qualified electrician. Alternatively please order the special version from the factory by contacting your local Carrier dealer.
For unit sizes 200 and 240 the installation requires drilling a hole into the control box, changing of the front door, and adapting the bus bar to be able to install the new
fused disconnect switch which is larger than the one used for the standard units.To order this special version from the factory, contact your local Carrier office.

*** Shows the new protection values with higher-capacity fuses than those specified in the previous column. If such fuses are part of the electrical installation upstream of
the unit, this is sufficient as anti-short circuit protection to the specified level, without additional protection.
**** If a protection device, other than the recommended fuses above, is used for the installation to ensure that no additional protection is required, the protection device must
have the specified thermal limit (I
the specified protection fuses from the previous columns must be installed.
