1. Purpose:
The JZB-200 series static relay with holding intermediate is a static relay used in power system relay protection and various automatic control circuits to increase the number and capacity of contacts in protection and control circuits.
2. Substitution: The external dimensions, terminal numbers, and wiring of the intermediate relays in this series are exactly the same as those of the original electromagnetic intermediate relays DZ, DZJ, DZS-200, DZB-200, and DZ-70 series. They are embedded plug-in structures that can be directly substituted and installed conveniently.
