I have, rightly or wrongly, just bought a Chinese VFD & spindle. Can anyone tell me if the following thermal overload relay would protect it in the case of jamming etc. If not is there any way of doing this?
The product is mainly applicable to a circuit of AC 50Hz/60Hz, rated working voltage up to 690V and current from 0.1A to 630A, used to protect a motor from overload, phase-failure, extra-long time starting and extra-long time jam. It can be installed inserting in a corresponding AC contactor or be installed independently.NR2(JR28) series relays can replace JRS1 series thermal overload relays.
