The Auxiliary Contact category at Roshanex lists add-on contacts and contact blocks for contactors and circuit breakers. Panel builders and electricians fit them when a control circuit needs extra signalling or interlocking.

Most items come from ABB, including the CA4, CA5X, CAL18 and CAL19 blocks. There are also HK1 units, as well as signal contacts for A1, A2 and A3 breakers. Because each auxiliary contact matches a particular series, check your contactor or breaker model before you order.

If you are unsure which part fits, send us the model number. Our team will help you choose, and we deliver across Pakistan.
