Short Circuit Protection
Protection Co-ordination, Type 1 vs Type 2:
Type 1 protection implies that after a short circuit, the device under test will no longer be in a functioning state. In type 2 co-ordination the device under test
will still be functional after the short circuit. In both cases, however the short circuit has to be interrupted. The fuse between enclosure and supply shall not
open. The door or cover of the enclosure shall not be blown open. There shall be no damage to conductors or terminals and the condcutors shall not sepa-
rate from terminals. There shall be no breakage or cracking of insulating bases to the extent that the integrity of the mounting of live parts is impaired.
Discharge of parts or any risk of fire shall not occur.
The product variants listed in the table hereunder are suitable for use on a circuit capable of delivering not more than 5,000 A rms Symmetrical Amperes, 600
Volts maximum when protected by fuses. Tests at 5,000 A were performed with RK5 fuses, time delay; please refer to the table below for maximum allowed
ampere rating of the fuse. Use fuses only.
