PLZA Range | Stainless Steel Restrained Plugs and Sockets

The PLZA Restrained Range of plugs and sockets are suitable for use in mining, tunnelling, pumping, and commercial applications, including Group 1 hazardous environments.

Ex-certified, PLZA Range plugs and sockets have an operating voltage of 1,100V and are rated for 425A. Though products within this range are designed for use in underground operational sites, they can also be utilised in opencast and metalliferous sites if a higher level of durability is required. In the event of damage to the PLZA’s flamepath, the outer body casting of PLZA plugs can be replaced on-site, even underground, assisting in the reduction of operational downtime and associated maintenance costs. No specialised training or cable termination is required, with this outer body able to be ordered separately and kept on-site.

Available release options for PLZA sockets include the Jack-In (Screw) Release, Quick Release, and the Ratchet Release, which is exclusive to KonNx Africa. Sockets within this range are also available in Receptacle Gland & Bracket (RGB) and Back-to-Back (B2B) assemblies.
