Emerson R399 Compact Central Office Protectors

R399 & AR399 Central Office Connectors

 The R399 is the highest density 100-pair connector available that utilizes industry standard 5-pin protector modules and is UL Listed to meet specification number UL 497 and is RUS accepted when used with S3AB, 3AB, 6A20, or 3GUVS protector modules. Its compact design, only 8.5-in. high, allows maximum density per frame vertical.

Made of a polycarbonate-blend, connectors can be factory stubbed with 22- or 24-gauge cable in 10-ft. increments, starting at 20 feet. The swivel stub is complete with a moisture dam and grounding harness. The connector utilizes a 6AWG grounding harness and is available with or without isolated ground. The connector is available in either a conventional, R399, or angled version, AR399. The angled version provides greater visibility and access to the protector module field, while retaining front access to both jumper field and test fields. The front-facing equipment field offers a choice of termination: wire-wrap or bifurcated quick-clips. Front and rear snap-through fanning strips facilitate orderly jumpering and offer highly visible pair count identification. The 100-pair front-facing test field makes testing easy.
