NEMA connectors are referred to a combination of plugs and receptacles used as twist-lock device in AC/DC power systems in North America and other countries. NEMA governs the standards of plugs and receptacles type connectors in the US and Canada. When it comes to protecting IT equipment, the power quality products and components play a crucial role and its paramount to provide a correct combination of plug and receptacles. With NEMA connectors, numerous output combinations are possible to match a large variety of requirements in Data Center PDU applications.

Elcom NEMA receptacles are especially designed for the North American market. These receptacles are known as the twist lock receptacles because the mating plug can be locked in the receptacle by twisting it after insertion. Elcom has been a pioneer in the design and development of NEMA twist-lock connectors. The locking connectors using curved blades make a more reliable connection in commercial and industrial wiring, where the electrical systems require protection from vibration or sudden impact. Elcom International offers the most common NEMA configurations for use in North America for 125ac and 250Vac single phase systems.

Available Receptacle combination : 5-15R, 5-20R, L5-20R, L5-30R, L6-20R, L6-30R, L14-30R
Available Plug combination: L5-20P, L5-30P, L6-20P, L6-30P, L21-20P, L21-30P
