The Terminal Blocks category at Roshanex lists add-on blocks for control panels and switchgear. Right now, it features the Autonics SA-CA contact block, which adds extra contacts to a control device. It also includes the Hyundai HOKZE1 and HOKZE2 electronic timer blocks.

Panel builders and maintenance electricians use these blocks when they extend a contactor or switch with extra functions. For example, a timer block can delay a contactor action in a motor starter circuit. Check that each block matches your device model, then order online with delivery across Pakistan.
