[ 1 ] Capacity of non-fuse breaker
for loom
(1) The non-fuse circuit breaker for loom is required to be installed on the switchboard for disconnecting the
power for loom maintenance, inspection or troubleshooting.
(2) It is recommended to provide one non-fuse circuit breaker for each weaving machine.
(3) Frequent tripping will occur if the capacity is insufficient.
(4) Determine the capacity of the non-fuse circuit breaker according to the current flowing through the
weaving machine (see Subsect. 1.3.3, [ 2 ] and [ 3 ]), the types of installed power transformer and power
supply, and the wiring length.
(5) The capacities on non-fuse circuit breakers obtained by the rough calculation formula are shown in the
table below for reference. Please check if the installed cable can be protected by the non-fuse breaker
selected according to the table.
Note that these values do not include the power consumption of a jacquard.
