HA inserts provide separable multipole connections with protective earth contacts. The HD01-HA model family includes compact 3A inserts and longer 10A, 16A and 32A formats. M and F identify male and female screw versions; MS and FS identify cage-clamp versions; MC and FC identify crimp versions. Housing size codes are mechanical designations, not current ratings.

HA-032 assemblies use two 16-position blocks, numbered 1–16 and 17–32, each with a PE provision. Choose the correct contact layout, gender, termination and enclosure interface. Membership of the HA family does not establish interchangeability between contact counts or with other connector families.
