Notes:

1. All the models also could be marked or used for the actual applications which have less contact ratings than the certificated

ratings. The rating can be Voltage, FLA, LRA or RES.

2. All the ratings have no “Break All Lines” restriction, except the rating “600VAC 50FLA/200LRA” for “XMC0-50 without Z” and 

“600VAC 63FLA/240LRA” for “XMC0-63 without Z”.
