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 condcutors
ot terminals and the condcutors shall not separate 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 100,000A rms
Symmetrical Amperes, 600Volts maximum when protected by fuses. Tests at 100,000A were performed with Class J, fast acting; please
refer to the table below for maximum allowed ampere rating of the fuse. Use fuses only.
