Echoflex ERDRC equivalent with ELED

Hi everyone,

I'm a technician support for Regulvar inc. from Quebec City and i'm new on the forum then thank you for your futur technical support.I'm some awareness on Echoflex product ERDRC, ERM, PTM, MOS and so on and i would like to know what is the equivalent of all Echoflex product, since he belonged to the group with ETC?

Is there a list of the old models versus the new ones? Example ERDRC-FCU (120/277/347V) --> ELED1 (120/277V) / ELED1H (240/347V)

In ELED1/ELED1H, there is an -AU? What does it mean?

Thank for your help
