Test buttons and plugs for R15.
Test buttoms without contact locking function are recommended for relays R2N ... WT, R3N ... WT, R4N ... WT, R15 ... WT 2P, R15 ... WT 3P, in which the possibility of permanent contact blocking is excluded. By manually pressing the button, we can put the relay into operation. The R4W-0003 or R15-M203 end caps replace the T-type button on relays with standard WT equipment and eliminate the function of testing and blocking contacts.
