Switching frequency in Make/Break operation:
180 operating cycles/hour for all the ratings
(ii) Aux Circuit:
Inbuilt Auxilliary Contacts
1NO + NC in case of 42.J36A
(iii) Control Circuit:
·
Control voltage is marked on the coil of the contactor.
Note:
·
The voltage is to be maintained within allowable
limits .
·
Operation on under voltage conditions to the coil may
cause damage to the coil/contactor.
·
Maximum back-up fuse rating for control circuit= 10A
