1.6 Ratings
The following tables provide information on contactor
withstand and closing current ratings (WCR).
Figure 1-5 provides WCR when used with any
current-limiting fuse or any overcurrent protective
device. Figure 1-6 and Figure 1-7 provides WCR when
coordinated with specific manufacturer’s circuit
breakers or fuse types. Figure 1-6 has ratings for
480 V maximum and apply to both UL and CSA listings.
Figure 1-7 has ratings for 600 V maximum and apply to
a CSA listing only.
