SYSTEM POWER DEVICES
•
have an interrupt capability no less than the short circuit rating (Prospective Short-
circuit Symetrical Amperes) of the Branch Circuit supplying the drive.
Restricted - If the Branch Circuit supplying power to the drive is capable of delivering
between 5,000 and 100,000 RMS symetrical short circuit amperes (250V maximum),
the fuse type provided for Protection has “Clearing I
2
t” restrictions, and must meet the
following requirements:
•
meet both of the requirements for a non-restricted fuse (above)
•
be a Class RK1, J, or CC dual element current limiting fuse
The requirements for both restricted and non restricted fuses may be meet by using a
single fuse that meets all requirements. The easiest way to accomplish this is to use a
“Current Limiting Fuse” from
Table 4-3 . These fuses meet all of the requirements for
both Short Circuit Protection and Over Current Protection, and may be used on
Branch Circuits that supply up to 100,000 RMS symetrical short circuit amperes (240V
maximum).
The maximum fuse size allowed for use with each S200-DLS Drive, as well as
suggested Bussmann fuses that meet both the restricted and non-restrictive
requirements as described above, is listed in
Table 4-3 .
UL REQUIREMENTS
• In order to meet UL requirements for the S200-DLS Drive, the over-current
protection device (fuses) must be UL-Listed Class RK1, J, or CC.
• The S21260-DLS must use Class J fuses, 30A or higher for protection.
