(1) Basic Requirements for Type 1 Coordination: Under the short-circuit condition, the starter shall cause no danger to persons or the installation. The starter may not be suitable for further service
without repair or replacement of parts. For further details, See UL508/CSA C22.2 No. 14 and EN 60947-4-2.
(2) Consult local codes for proper sizing of short-circuit protection.
(3) High capacity fault ratings when used with a time delay Class J fuse or time delay Class L fuse.
(4) Circuit Breaker must be of the designated 140G Frame size.
(5) Other circuit breakers pending.
